Problems solved by technology

However, automotive wheel nuts are highly susceptible to corrosion due to the wet and salty environment to which vehicle wheels are typically exposed
Naturally, corrosion on the visible surface of the wheel nut greatly detracts from the aesthetics of the wheel (and the car in general)

Embodiment Construction

[0060] Referring now to the accompanying drawings, figure 1 A conventional stainless steel capped automotive wheel nut 10 is shown. Typically, the top of the nut body 12 , including the wrenching surface 14 , is covered by a stainless steel cap 16 . Thus, the nut body 12 itself is not visible to the casual observer when the nut 10 is mounted on a wheel, and the stainless steel cap 16 is the only readily visible portion of the nut 10 . However, the bottom of the nut body 12 is not covered by the cap 16 so that the nut 10 can be screwed onto the wheel without the cap 16 interfering with the threaded engagement.

[0061] figure 2 A conventional tool 18 for crimping the cap 16 onto the nut body 12 is shown. As shown, the nut body 12 is inserted into the cap 16 and the nut body 12 and cap 16 are received within the fastener holder 20 . Such as figure 2 As shown on the left, the crimping head 22 is then moved toward the fastener holder 20 and the angled surface 24 contacts t...

Abstract

The capped fastener is provided with two outer flanges and a groove therebetween. The cap crimps over the first outer flange without covering the second outer flange. The end of the cap is crimped in the groove between the first outer flange and the second outer flange. A crimping tool and crimping method for crimping the end of the cap into the groove located between the two outer flanges is also provided.

Description

[0001] related application [0002] Pursuant to Title 35, United States Code, Section 119(e), this patent document claims the benefit of the filing date of U.S. Provisional Patent Application Serial No. 62 / 103,898, filed on January 15, 2015, which is incorporated herein by reference . technical field [0003] The present invention relates generally to fasteners, and more particularly to fasteners with caps crimped over flanges. Background technique [0004] Fasteners are used in a variety of applications to attach various components together. Typically, a fastener has at least a threaded portion and one or more wrenching surfaces thereon. The wrenching surface is designed to receive torque from a tool, such as a socket wrench or other wrench, used to tighten or loosen a fastener. In conventional fasteners such as nuts, the fastener may have internal threads and six wrenching surfaces oriented in a hexagonal shape around the internal threads. However, other fasteners may...
