Free Spinning Washer-Nut Assembly
US Patent:
4132145, Jan 2, 1979
Filed:
Apr 11, 1977
Appl. No.:
5/786170
Inventors:
Charles H. Becker - Braintree MA
Assignee:
TRW Inc. - Cleveland OH
International Classification:
F16B 3700, F16B 3924
US Classification:

Abstract:
A washer-nut assembly wherein a sheet metal nut is rotatably coupled within an annular plastic washer. The nut has an inner threaded barrel portion for engaging the threads of a cooperating bolt, an outer barrel portion shaped for engagement by a tightening tool and a frusto-conically shaped skirt portion extending outwardly from the outer barrel portion. The washer includes a central through-aperture and an inboard surface near one end of the washer that defines a seat for the skirt portion of the nut. The axial height of the washer is substantially greater than that of the nut so that the nut is recessed within the washer. The nut is coupled to the washer by skiving material from the inboard surface of the washer to form tongues that overhang the skirt portion of the nut. The tongues retain the nut within the washer yet permit free-spinning of the nut and washer relative to one another.
