Abstract
Abstract A nut which has a conical end extending into a cylindrical land portion. The land portion connects the conical end with a chamfered portion of the nut head which is covered with a hard corrosion resistant cap extending all around the sides of the nut head. The cap is crimped around the upper end of the nut head to retain a disc or button to close the cap of the nut. The portion of the cap adjacent the chamfered portion of the nut head is formed into a radial flange, which in assembly is crimped against the chamfered portion of the nut head to provide a secure sealing engagement of the button on the nut.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A capped nut assembly comprising in combination: a nut having top and bottom surfaces, a plurality of planar side surfaces, an annular chamfer contiguous with the side surfaces and between the side surfaces and the bottom surfaces, and a threaded bore extending between the top and bottom surfaces, a cap of resilient material disposed over the nut and having a plurality of side surfaces overlying the side surfaces of the nut to prevent relative rotation between the cap and the nut, a top having an in-turned rim defining an aperture, a decorative disc overlying the top surface of the nut and engaged by said rim, said cap having formed thereon a radial flange defining a flat, annular surface parallel to said bottom surface and an internal radial edge which engages said chamfer such that tightening the nut against a fixed surface causes the radial edge to resiliently move up the chamfer and force said rim into increasingly tighter engagement with said disc.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
18 words
