Tolerance compensating mounting device
The invention comprises a tolerance compensating mounting device comprising a bushing having an internal and external thread. The bushing is threaded into a part to be mounted to a surface. A bolt is then threaded into a bushing bore using the internal threads. The internal threads cause an interference fit between the bolt shank and the threads, temporarily preventing further insertion of the bolt. The bolt is then turned further, thereby turning the bushing and causing the bushing to unscrew from the part toward the mounting surface until the bushing seats on the mounting surface, thereby completely compensating for a tolerance gap. As the bolt is turned further, at a relatively low torque the sacrificial internal threads are stripped allowing the bolt to be fully torqued into the mounting surface hole, thereby simultaneously connecting the components with a properly torqued connection while compensating for a tolerance gap.

Blindly installed, reinforceable nuts for joining structural members
InactiveUS20060078399A1Improve continuityIncreased shear strengthNutsScrewsInterference fitEngineering
A blind nut installed in a structural joint provides an interference fit and a fatigue enhancing benefit to the structural joint. A bolt can be inserted into the nut for additional shear strength and shear continuity. During installation in the structural joint, a first flange of the nut is seated against a first structural member, an installation tool is inserted into a passage in the nut, and the tool is operated to buckle a collapsible portion of the nut to form a second flange on a second structural member. Contemporaneously, an expandable portion of the nut is radially expanded into the structural joint. The installation process induces a high interference fit and may also induce a residual compressive stress in the structural joint.

Advanced nut and bolt
A vibration resistant fastening system including a high fatigue strength bolt made from a first material and a nut made from a second material that is softer than the first material of the bolt. The bolt includes bolt threads and the nut includes pre-tapped nut threads that match with the bolt threads. The fastening system utilizes a combination of unique geometry of the nut and bolt threads and a hardness differential between the nut and bolt to provide vibration resistance. When tightened, crests of the bolt threads embed into the soft bearing flanks of the nut threads. Simultaneously with the bolt crest embedment, the softer nut thread crests flow radially inward into the root radius of the bolt threads. This complete contact between the nut and the bolt restricts the nut from moving in a transverse direction relative to a longitudinal axis of the bolt.

Bolt and process for producing a protective layer on a bolt
The invention relates to a process for producing a protective layer on a bolt, in which an aluminum-containing high-temperature lacquer is first of all applied to the bolt and then cured and stoved at a defined stoving temperature. The screw thread is additionally lubricated prior to installation of the bolt. This process reduces oxidation and ultimately reduces seizing of the screw connection.

Panel fastening and waterproofing anchor
A self-anchoring fastening device for laminating sheets of material such as sheets of metal used in constructing metal buildings. The anchor comprises a collapsible anchoring portion having radially expanding anchoring strips, which will not pull out of a hole drilled in the sheets. Threads internal to the expandable anchor cooperate with threads on a bolt inserted therein to collapse the expandable anchor, providing anchoring strips over one sheet such that the expandable anchor cannot be pulled out of the hole. A washer between the base of the collapsible anchoring portion and one sheet provides for a waterproof fastener such that the building will be watertight. The anchor is easy to install by placing the anchoring device though aligned apertures in two sheets and then turning the bolt relative to the collapsible anchoring portion to extend the radially expanding strips thus securing one sheet to the other.

High-capacity radial fit coupling bolts
A high capacity radial-fit coupling bolt (or “expanding sleeve bolt”) has a pair of tapered sleeves about a shank of a bolt to which can be applied a tensioning load. An extrudable ring, or a compression ring, is interposed between a head nut or head flange at one end of the shank, and one end of an inner sleeve. A tensioning load is applied to the shank, the inner sleeve causing the outer sleeve to expand diametrically. At a preset load limit, the extrudable ring is extruded through at least one bore in a drive piston between the head nut and the extrudable ring, to allow shank to move relative to the inner sleeve until the tensioning load is fully applied. Alternatively, a drive member is provided between the head nut or head flange and the compression ring, and at a preset limit, the compression ring allows the shank to move relative to inner sleeve until the tensioning load is fully applied. The preset limit will typically correspond to the force required to fully expand the outer sleeve.
