[0002] This disclosure generally relates to an assembly comprising two bodies, fasteners, and a disposable nut. background

[0003] Fasteners, such as rivets or threaded bolts, are used to join two bodies. Typically, rivets do not loosen under load (e.g., vibration) and, compared to threaded bolts, can secure a joint with a relatively short clamping length (e.g., the total length of the fastener). However, installing and removing rivets is much more time-consuming than installing threaded bolts. Overview

[0004] Threaded bolts and nuts improve the ease of joining and disconnecting joints. Nuts can be removed during disassembly and reused during reinstallation. However, nuts can be lost after removal. Furthermore, reinstalling nuts can be difficult due to space constraints limiting access. For example, when a bolt is screwed into a nut using a socket, the structure around the nut may restrict access to a wrench used to hold the nut in place, or the structure around the bolt head may restrict access to a screwdriver used to tighten the bolt to the nut.

[0005] Some embodiments of this disclosure can be used to solve these problems.

[0006] In one embodiment, an assembly includes a first body, a second body, a fastener, and a nut. The first body includes an outer surface and an inner surface opposite to the outer surface.

The method also includes connecting the first body to the second body by setting the fastener shank through the second body through hole and the first body through hole and engaging the fastener threaded portion with the first body threaded portion such that the fastener head is located on the outer surface side of the second body.

[0023] In some embodiments, during the step of connecting the first body to the second body, the first body is connected to the second body without using a nut.

The drawings are provided to illustrate one or more embodiments, and it should be clearly understood that they are not intended to limit the scope or meaning of the claims. Detailed description

[0037] The following is a more detailed description of various related concepts and implementation methods for the assembly of a component comprising two bodies, fasteners, and a disposable nut. The various concepts described above and discussed in more detail below can be implemented in any of a variety of ways, as the described concepts are not limited to any particular implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

[0038] As used herein, "threaded" indicates having one or more threads. For example, a threaded surface or component may have one or more threads thereon. The one or more threads may be external (e.g., "male") threads or internal (e.g., "female") threads. A threaded surface or component may thread-engage another threaded surface or component. For example, the internal thread of an internally threaded surface may thread-engage the external thread of an externally threaded component. Through this threaded engagement, the two threaded components become connected.

[0039] As used herein, the terms "unthreaded," "non-threaded," "without threads," and similar terms are used to indicate that the surface does not have any threads. For example, a non-threaded surface or component does not contain threads. A non-threaded surface cannot be threaded onto a threaded surface.

[0040] I. Overview In an assembly, components may be connected to each other using fasteners such as threaded bolts. It should be understood that the discussion of assemblies comprising two components herein similarly describes assemblies comprising one or two conduits (e.g., instead of one or two components), unless explicitly stated otherwise.

[0041] The first component can be coupled to the second component in a first configuration during the initial assembly process. When another component is assembled on or near the first and second components, it may become difficult to disconnect the first component from the second component (e.g., when repairing or replacing at least one of the first or second components) and subsequently reconnect the first component to the second component (e.g., after repairing or replacing at least one of the first or second components, etc.). Therefore, it is desirable to improve the ease of disconnecting and reconnecting components to improve the ease of repairing at least one of the first or second components.

[0042] The embodiments described herein relate to an assembly comprising two bodies, fasteners, and a disposable nut that improves the ease of disconnection and reconnection of the assembly. The assembly includes a component assembly and a conduit assembly. In other embodiments, the assembly may include a first component assembly coupled to a second component assembly or a first conduit assembly coupled to a second conduit assembly. The component assembly is coupled to the conduit assembly via fasteners. For example, the component includes a first flange having an outer surface and an inner surface opposite to the outer surface. The first flange includes a through-hole that is at least partially threaded. The conduit assembly includes a second flange having an outer surface and an inner surface opposite to the outer surface. The inner surface of the second flange faces the inner surface of the first flange. The second flange includes a non-threaded through-hole. Each fastener includes a fastener shank having a threaded portion and a non-threaded portion. When the assembly is initially assembled, each fastener shank extends through the through-holes of the first and second flanges such that the non-threaded portion aligns with the threaded through-hole of the first flange. Each fastener engages a corresponding nut at the outer surface of the second flange.

[0043] The embodiments described herein also include methods for disassembling components and reassembling them in a different (e.g., second) configuration. After initial assembly, disconnecting the component assembly and conduit assembly may be difficult. For example, the presence of surrounding components may interfere with disconnecting the component assembly from the conduit assembly and subsequent reconnection. The embodiments described herein advantageously improve the ease of disconnecting and reconnecting the components. The component assembly is disconnected from the conduit assembly by disengaging the fastener from the corresponding nut. When the component assembly is reconnected to the conduit assembly (e.g., after a maintenance event, etc.), a fastener is positioned through a through-hole in the second flange and through a through-hole in the first flange, such that the threaded portion of the fastener engages the threaded through-hole in the first flange. Advantageously, the nut is not used for reconnecting the assembly, allowing the assembly to be reconnected by approaching only one side of the assembly (e.g., the outside of the second flange).

[0044] II. Overview of Example Components refer to Figure 1 The diagram shows a perspective view of component 100 according to an example embodiment. As explained in more detail herein, component 100 includes two bodies (e.g., flanges) selectively coupled together. One of these bodies may be part of a component (e.g., an exhaust aftertreatment system component), and the other body may be part of a conduit (e.g., an exhaust aftertreatment system conduit). Component 100 facilitates the disconnection and reconnection of the bodies in a faster and simpler manner by enabling bolts to be reinstalled without nuts and in a manner different from how the bolts were previously installed. In this way, component 100 is more desirable than other systems that require the reuse of nuts and the reinstallation of bolts in the same manner as the bolts were previously installed.

[0045] Component 100 includes component assembly 110. In some embodiments, component assembly 110 is or includes a component of an exhaust aftertreatment system (i.e., a "treatment system"). Component assembly 110 may include catalyst components (e.g., oxidation catalysts, selective catalytic reduction catalysts, etc.), filters (e.g., particulate filters), etc. In other embodiments, component assembly 110 is not part of the exhaust aftertreatment system. Component assembly 110 may be coupled to another component, such as a duct assembly.

[0046] Component assembly 110 includes a component body 112. As shown, the component body 112 is substantially cylindrical in shape. More specifically, the component body 112 is shown as including an extension 114 and a restricted portion 116. The extension 114 has a first diameter, and the restricted portion 116 has a second diameter smaller than the first diameter. The distance between the extension 114 and the restricted portion 116 is relatively small (e.g., compared to the first diameter or the difference between the first and second diameters).

[0047] In some embodiments, coupling component assembly 110 to another component, such as a conduit assembly, can be difficult. For example, the difference between the first and second diameters, the relatively small distance between the extension portion 114 and the limiting portion 116, and / or the presence of surrounding components (e.g., components coupled to or not coupled to component assembly 110) can combine to interfere with coupling component assembly 110 to the other component. Advantageously, these difficulties are minimized if component assembly 110 is coupled to the other component before some or all of the surrounding components are located near component 100.

[0048] It should be understood that Figure 1 The shape of the component body 112 shown is merely an example, and the component body 112 can have different shapes (e.g., cylindrical, rectangular, etc.).

[0049] Component assembly 110 includes a first body 120. The first body 120 may be a flange, such as a component body flange. As used herein, a "flange" refers to a plate having two planes parallel to each other and extending about an opening. Furthermore, a "flange" may include more than one fastener opening, allowing the flange to be engaged to another flange using multiple fasteners. While a component body flange is an example of the first body 120, the first body 120 is not limited to being a flange.

[0050] like Figure 1 As shown, the first body 120 extends outward from the component body 112. More specifically, the first body 120 extends radially outward from the outer surface of the component body 112. The first body 120 includes an outer surface 122 and an inner surface 124 opposite to the outer surface 122.

[0051] like Figure 2 As shown, the first body 120 includes a first body through-hole 126. The first body through-hole 126 extends through the first body 120 (e.g., from the outer surface 122 to the inner surface 124). As shown, the first body 112 includes four first body through-holes 126. It should be understood that the first body 112 may include more or fewer first body through-holes 126 (e.g., at least one of the first body through-holes 126). Each of the first body through-holes 126 is centered on a corresponding axis that is substantially perpendicular to the inner surface 124 and the outer surface 122, such that each of the corresponding axes is parallel to each other.

[0052] like Figure 4 and Figure 5 As shown, the first main body through hole 126 includes a first main body threaded portion 128. The first main body threaded portion 128 is threaded. In some embodiments, and as... Figure 4 As shown, the threaded portion 128 extends along the length of the through hole 126. In some embodiments, the threaded portion 128 extends from the outer surface 122 to the inner surface 124. In other embodiments, and as... Figure 5 As shown, the threaded portion 128 extends only partially between the outer surface 122 and the inner surface 124, such that the through hole 126 includes a non-threaded portion 130. For example, the threaded portion 128 extends from the outer surface 122 toward the inner surface 124, and the non-threaded portion 130 extends from the threaded portion 128 to the inner surface 124.

[0053] In any of the above embodiments, the threaded portion 128 is configured to engage the threaded portion of the fastener. The threaded portion 128 does not engage the non-threaded portion of the fastener. The non-threaded portion 130 does not engage either the threaded portion or the non-threaded portion of the fastener. In this way, the fastener can rotate and / or translate relative to the first body through-hole 126, while the fastener does not engage the non-threaded portion 130. In some embodiments, the non-threaded portion 130 does not contact the fastener disposed in the first body through-hole 126. In other embodiments, the non-threaded portion 130 contacts but does not engage the fastener disposed in the first body through-hole 126.

[0054] Return to reference Figure 1 Component 100 includes catheter assembly 140. Catheter assembly 140 includes catheter body 142. As shown, the catheter body 142 is substantially cylindrical in shape. It should be understood that... Figure 1 The shape of the catheter body 142 shown is merely an example, and the catheter body 142 can have different shapes (e.g., rectangular, etc.).

[0055] In some embodiments, the duct body 142 is or includes a component of an exhaust aftertreatment system. For example, the duct body 142 may be a duct (e.g., a tailpipe) that fluidly connects an upstream component to a downstream component or fluidly connects an upstream component to the atmosphere.

[0056] The catheter assembly 140 can be coupled to the component assembly 110. As described above, when the component assembly 110 is coupled to another component (such as the catheter assembly 140), it may be difficult to disconnect the component assembly 110 and the catheter assembly 140. For example, the difference between the first diameter and the second diameter, the relatively small distance between the extension portion 114 and the limiting portion 116, and / or the presence of surrounding components (e.g., components coupled to or not coupled to the component assembly 110 or the catheter assembly 140) may combine to interfere with coupling the component assembly 110 to the catheter assembly 140. Advantageously, these difficulties are minimized when the component assembly 110 is coupled to the catheter assembly 140 before some or all of the surrounding components are located near the assembly 100.

[0057] The catheter assembly 140 includes a second body 150. The second body 150 may be a flange, such as a catheter body flange. While a catheter body flange is an example of a second body 150, the first body 150 is not limited to being a flange.

[0058] The second body 150 extends outward from the catheter body 142. More specifically, the second body 150 extends radially outward from the outer surface of the catheter body 142. The second body 150 includes an outer surface 152 and an inner surface 154 opposite to the outer surface 152. Figure 4 and Figure 5 As shown, the inner surface 154 of the second body 150 faces the inner surface 124 of the first body 120.

[0059] like Figure 4 and Figure 5 As shown, the second body 150 includes a second body through-hole 156. The second body through-hole 156 extends through the second body 120 (e.g., from the outer surface 122 to the inner surface 124). The second body through-hole 156 is unthreaded. The second body through-hole 156 does not engage the threaded portion of a fastener and does not engage the unthreaded portion of a fastener. In this way, the fastener can rotate and / or translate relative to the second body through-hole 156 without engaging the second body through-hole 156. In some embodiments, the second body through-hole 156 does not contact a fastener disposed in the second body through-hole 156. In other embodiments, the second body through-hole 156 contacts but does not engage a fastener disposed in the second body through-hole 156.

[0060] In an example embodiment, the second body 150 includes four second body through holes 156. It should be understood that the second body 150 may include more or fewer second body through holes 156 (e.g., at least one of the second body through holes 156). Each of the second body through holes 156 is centered on a corresponding axis substantially perpendicular to the inner surface 154 and the outer surface 152, such that each of the corresponding axes is parallel to each other. When the component assembly 110 is coupled to the conduit assembly 140, each second body through hole 156 is aligned with a corresponding first body through hole 126. In this way, fasteners can be installed through the first body through hole 126 and the corresponding second body through hole 156.

[0061] Component 100 includes a sealing member 160. The sealing member 160 is disposed between a first body 120 and a second body 150. More specifically, the sealing member 160 is disposed between the inner surface 154 of the second body 150 and the inner surface 124 of the first body 120. Figure 4 and Figure 5 As shown, the sealing member 160 contacts the inner surface 154 of the second body 150 and the inner surface 124 of the first body 120. In this way, the sealing member 160 forms a seal between the inner surface 154 of the second body 150 and the inner surface 124 of the first body 120. In this way, the sealing member 160 can substantially prevent the flow of fluids (e.g., gases, liquids, air, water, etc.) between the inner surface 124 of the first body 120 and the inner surface 154 of the second body 150 (e.g., in the radial direction). In various embodiments, the sealing member 160 is made of suitable materials such as TEFLON®, rubber, polymers, elastomers (e.g., nitrile rubber, cryogenic nitrile rubber, ultra-low temperature nitrile rubber, ultra-high temperature nitrile rubber, butyl rubber, ethylene propylene rubber, fluoroelastomers, acrylonitrile butadiene rubber, ethylene oxide epichlorohydrin rubber, etc.), natural or synthetic leather, fabrics, any other suitable materials, or combinations thereof.

[0062] like Figure 3 As shown, the sealing member 160 includes a sealing member through-hole 162 formed therethrough. In the illustrated embodiment, the sealing member 160 includes four sealing member through-holes 162. It should be understood that the sealing member 160 may include more or fewer sealing member through-holes 162 (e.g., at least one of the sealing member through-holes 162). When the component assembly 110 is coupled to the conduit assembly 140, each sealing member through-hole 162 is aligned with a corresponding first body through-hole 126 and a corresponding second body through-hole 156. In this way, fasteners can be provided through the first body through-hole 126, the corresponding second body through-hole 156, and the corresponding sealing member through-hole 162.

[0063] Return to reference Figure 1Component 100 includes fasteners 170. Component 100 includes a number of fasteners equal to the number of first body through holes 126. Component 100 includes a number of fasteners equal to the number of second body through holes 156. Advantageously, and as described in more detail herein, due to the presence of the threaded portion 128 of the first body through hole 126, the fasteners 170 can be selectively configured in a first configuration (e.g., Figure 4 and Figure 5 The configuration shown) or the second configuration (e.g., Figure 7 (As shown in the configuration) Installation.

[0064] As described above, coupling component assembly 110 to conduit assembly 140 can be difficult. For example, the difference between the first and second diameters, the relatively small distance between the extension portion 114 and the limiting portion 116, and / or the presence of surrounding components (e.g., components coupled to component assembly 110 or conduit assembly 140 and / or components not coupled to component assembly 110 or conduit assembly 140) can combine to interfere with coupling component assembly 110 to conduit assembly 140. Advantageously, these difficulties are minimized when component assembly 110 is coupled to conduit assembly 140 before some or all of the surrounding components are located near component assembly 100. For example, fastener 170 can be installed in a first configuration during the initial assembly of component 100 (e.g., when few or no other components are located near component assembly 110 or conduit assembly 140). After the initial assembly of component 100, fastener 170 can be installed in a second configuration, thereby increasing the ease of installation of fastener 170.

[0065] Each fastener 170 includes a fastener head 172 and a fastener shank 174. The fastener head 172 is located at the proximal end of the fastener shank 174. Figure 4 and Figure 5 As shown, the fastener shank 174 extends through the first body through-hole 126 and the second body through-hole 156. The fastener shank 174 includes a fastener threaded portion 178, which is provided at least at the distal end of the fastener shank 174, opposite to the fastener head 172. The fastener threaded portion 178 is threaded.

[0066] In some embodiments, the fastener shank 174 includes a threadless portion 180. The threadless portion 180 extends between the fastener head 172 and the threaded portion 178. Figure 4 and Figure 5As shown, the unthreaded portion 180 of the fastener is positioned close to the threaded portion 128 of the first body through-hole 126. Advantageously, the unthreaded portion 180 of the fastener does not engage the threaded portion 128 of the first body through-hole 126, such that the fastener 170 can rotate and / or translate relative to the first body through-hole 126 without engaging the threaded portion 128 of the first body through-hole 126.

[0067] The fastener head 172 is substantially hexagonal in shape. The fastener head 172 may have a first length between 17 mm and 145 mm, measured between two flat portions of the hexagonal shape. The fastener head 172 may have a second length between 18.84 mm and 167.43 mm, measured between two corner portions of the hexagonal shape. The fastener head 172 is disposed on the outer surface side of the first body 120. The fastener head 172 is disposed close to the outer surface 122 of the first body 120. The fastener head 172 contacts the outer surface 122 of the first body 120.

[0068] In some embodiments, the threaded portion 178 of the fastener does not engage the first body threaded portion 128. The unthreaded portion 180 of the fastener may be aligned with the first body threaded portion 128 such that no part of the fastener shank 174 engages the first body threaded portion 128.

[0069] In some embodiments, at least a portion of the fastener threaded portion 178 is aligned with the second body through-hole 156. In these embodiments, the fastener threaded portion 178 does not engage any portion of the second body through-hole 156 (e.g., because the second body through-hole 156 is unthreaded).

[0070] In some embodiments, when the entire fastener shank 174 is threaded (e.g., the fastener threaded portion 178 extends along the length of the fastener shank 174), the fastener threaded portion 178 engages the first body threaded portion 128. In these embodiments, the engagement of the fastener 170 with the first body 120 does not provide a coupling function.

[0071] Return to reference Figure 1 Component 100 includes nuts 190. Component 100 may include a number of nuts 190 equal to the number of fasteners 170. That is, each fastener 170 may have a corresponding nut 190. Figure 4 and Figure 5 As shown, each nut 190 includes a nut body 191. Each nut 190 includes a nut through-hole 192 extending through the nut body 191. Each nut 190 includes a nut threaded portion 194. More specifically, the nut through-hole 192 includes the nut threaded portion 194. That is, the nut through-hole 192 is threaded.

[0072] In some embodiments, the nut body 191 is substantially hexagonal in shape. The nut body 191 may have a first length between 17 mm and 145 mm, measured between two flat portions of the hexagonal shape. The nut body 191 may have a second length between 18.84 mm and 167.43 mm, measured between two corner portions of the hexagonal shape.

[0073] In some embodiments, the nut body 191 and the fastener head 172 are substantially the same shape and size, such that tools of the same size (e.g., sockets, wrenches, etc.) can be used to manipulate (e.g., rotate, etc.) the fastener 170 and the nut 190. Advantageously, when the nut body 191 and the fastener head 172 are substantially the same shape and size, the installation and subsequent removal of the fastener 170 and the nut 190 are performed using two tools of the same size. Furthermore, during subsequent assembly of the assembly 100, the installation of the fastener 170 can be performed using either of these tools (e.g., if removal requires two tools of different sizes, it is not necessary to select the correct one from two different sized tools).

[0074] Nut 190 is disposed on the outer surface side of the second body 150. Nut 190 is disposed close to the outer surface 152 of the second body 150. Nut 190 contacts the outer surface 152 of the second body 150. The threaded portion 194 of the nut engages the threaded portion 178 of the fastener. In this way, the fastener 170 and the nut 190 cooperate to connect the first body 120 to the second body 150.

[0075] Nut 190 is used for the initial assembly of component 100. For example, during the initial assembly of component 100, when other parts or components are not located near component 100, nut 190 can thread-engage with fastener 170 without interference from other parts or components. In some embodiments, nut 190 is a flared nut 190. Flared nut 190 includes a nut flange 196. Nut flange 196 is disposed on a first side of nut body 191 and close to the outer surface 152 of second body 150. In some embodiments, nut flange 196 contacts the outer surface 152 of second body 150. Advantageously, nut flange 196 distributes compressive forces over a larger surface area (e.g., of second body 142), which mitigates stress accumulation near second through-hole 156.

[0076] Nut 190 is not used for subsequent assembly of component 100. For example, other parts and / or other components (e.g., frame, bracket, wiring, etc.) may make it difficult to access both the outer surface 122 of the first body 120 and the outer surface 152 of the second body 150 to position fastener 170 and nut 190 for engagement, respectively.

[0077] Now for reference Figure 6 and Figure 7 Various views of component 100 in a second configuration are shown. As shown, component assembly 110 is connected to conduit assembly 140 via fastener 170. More specifically, component assembly 110 is connected to conduit assembly 140 via fastener 170 without nut 190.

[0078] like Figure 7 As shown, the fastener shank 174 of the fastener 170 extends through the second body through-hole 154 and the first body through-hole 126. The fastener threaded portion 178 engages with the first body threaded portion 128. The fastener head 172 is located on the outer surface side of the second body 150. The fastener head 172 is disposed close to the outer surface 152 of the second body 150. The fastener head 172 contacts the outer surface 152 of the second body 150. As briefly described above, when the first body 120 is coupled to the second body 150 in this manner, the first body 120 is coupled to the second body 150 without the use of the nut 190.

[0079] In some embodiments, when the fastener shank 174 includes a fastener unthreaded portion 180, the fastener unthreaded portion 180 is positioned close to the second body through hole 156 such that the fastener unthreaded portion 180 does not engage with the second body through hole 156.

[0080] In some embodiments, when the entire fastener shank 174 is threaded (e.g., the fastener threaded portion 178 extends along the length of the fastener shank 174), the fastener threaded portion 178 engages the first body threaded portion 128, and the fastener threaded portion 178 does not engage the second body through hole 156.

[0081] As described above, after the initial assembly of component 100, it may be difficult to access both the outer surface 122 of the first body 120 and the outer surface 152 of the second body 150 (e.g., due to the presence of surrounding components). Advantageously, when the first body 120 is... Figure 7 When connected to the second body 150 in the manner shown, the user does not need to approach the outer surface 122 of the first body 120, thereby improving the ease of assembling the component 100.

[0082] III. Example methods for assembling, disassembling, and reassembling components Now for reference Figure 8 The figure illustrates a method 300 for assembling, disassembling, and reassembling component 100 according to an example embodiment. As shown, method 300 includes a first process 302 for assembling component 100 (e.g., in a first configuration, such as...). Figure 1(The configuration shown). Method 300 includes a second process 330 of disassembling component 100 and reassembling component 100. It should be understood that the first process 302 and the second process 330 may be performed sequentially, but may be performed by different participants.

[0083] In some embodiments, the first process 302 is performed by OEM employees, such as mechanics, technicians, or other persons associated with the OEM. In other embodiments, the first process 302 is performed by machines or automated assembly machines owned or operated by the OEM.

[0084] In some embodiments, the second process 330 may be performed by a mechanic, technician, or other person unrelated to the OEM. In other embodiments, the second process 330 is performed by a machine or automated assembly machine owned or operated by an entity other than the OEM, such as a repair shop.

[0085] The process 302 of assembling component 100 includes providing component assembly 110 at step 310. At step 312, fasteners 170 are inserted through each first body through-hole 126. In some embodiments, step 312 is performed after step 314 and / or after step 316. More specifically, the fastener shank 174 of each fastener 170 is inserted through the first body through-hole 126 of component assembly 110, as... Figure 2 As shown. In some embodiments, process 302 includes step 314. In step 314, the sealing member 160 is positioned at the inner surface 124 of the first body 120 such that the fastener shank 174 of the fastener 170 extends through the sealing member through-hole 162, as shown. Figure 3As shown. In some embodiments, when step 312 is performed after step 314 and / or after step 316, the sealing member 160 is positioned at the inner surface 124 of the first body 120 such that the sealing member through-hole 162 is aligned with the first body through-hole 126. At step 316, the conduit assembly 140 is positioned at the component assembly 110 such that the inner surface 154 of the second body 150 is disposed at the inner surface 124 of the first body 120, and the fastener shank 174 of the fastener 170 extends through the second body through-hole 156. In some embodiments, when step 312 is performed after step 316, the second body 150 is positioned such that the second body through-hole 156 is aligned with the first body through-hole 126. When step 312 is performed after step 316, the fastener shank 174 of each fastener 170 is inserted through the first body through-hole 126, the second body through-hole 156, and, in embodiments including the sealing member 160, through the sealing member through-hole 162. At step 318, nuts 190 are provided, and each nut is coupled to a corresponding fastener 170 by engaging a nut threaded portion 194 with a fastener threaded portion 178. In this way, the first body 120 is coupled to the second body 150.

[0086] As briefly described above, component assembly 110 can be disconnected from conduit assembly 140. When assembly 100 is in a first configuration (e.g., Figure 1 When assembled in the configuration shown, component 100 can be disassembled and assembled in a second configuration (e.g., Figure 6 (The configuration shown) is reassembled.

[0087] Process 330 includes providing, as described herein, at step 332. Figures 1-5The component 100 is described above. At step 334, the fastener 170 disengages from the nut 190. More specifically, the fastener threaded portion 178 of each fastener 170 disengages from the nut threaded portion 192 of each nut 190. At step 336, each fastener 170 is removed from its corresponding first body through-hole 126 and corresponding second body through-hole 154. More specifically, the fastener shank 174 of each fastener 170 is removed from its corresponding first body through-hole 126 and corresponding second body through-hole 154. As described above, in some embodiments, the fastener threaded portion 178 extends between the distal end of the fastener shank 174 and the fastener head 172, such that the fastener threaded portion 178 engages the first body threaded portion 128 before the fastener shank 174 is removed from the first body through-hole 126. In these embodiments, removing the fastener shank 174 from the first body through-hole 126 includes disengaging the fastener threaded portion 178 from the first body threaded portion 128. In other embodiments, the fastener shank 174 includes a fastener unthreaded portion 180 extending between the fastener head 172 and the fastener threaded portion 178, and the fastener unthreaded portion 180 is positioned near the first body threaded portion 128 before the fastener shank 174 is removed from the first body through-hole 126, such that the fastener unthreaded portion 180 can be translated relative to the first body through-hole 126 without engaging the first body threaded portion 128.

[0088] At step 338, by setting the fastener shank 174 through the second body through hole 154 and the first body through hole 152 and engaging the fastener threaded portion 178 with the first body threaded portion 128, the fastener head 172 is positioned on the outer surface side of the second body 150, thereby connecting (e.g., reconnecting) the first body 120 to the second body 150 without using the nut 190.

[0089] As described above, in the step of connecting the first body 120 to the second body 150, the first body 120 is connected to the second body 150 without using the nut 190. The nut 190 is not used for the reassembly of the assembly 100 because other parts and / or other components (e.g., frames, brackets, wiring, etc.) may make it difficult to access both the outer surfaces 122 of the first body 120 and the outer surfaces 152 of the second body 150 to position the fastener 170 and the nut 190 for engagement. After the initial assembly of the assembly 100, it may be difficult to access both the outer surfaces 122 of the first body 120 and the outer surfaces 152 of the second body 150 (e.g., due to the presence of surrounding parts). Advantageously, when the first body 120 is connected to the second body 150 as described in process 330, the user (e.g., a mechanic, technician, etc.) does not need to access the outer surface 122 of the first body 120. That is, the user can assemble the assembly 100 simply by accessing the outer surface 152 of the second body 150 to position the fastener 170, thereby improving the ease of assembling the assembly 100. Furthermore, during the reassembly of component 100, the installation of fastener 170 can be performed using only one of the tools used to disassemble component 100.
