ABSTRACT:
An attaching sleeve for a floating nut assembly is formed from rod or wire stock by successive cold heading or cold forming operations. The steps involve cutting off a longitudinal segment from the stock, forming a flange on the front end of the segment, forming a centrally disposed opening through the segment, and forming longitudinally extending ridges projecting outwardly around the periphery of the segment. The attaching sleeves made by the method of the present invention have accurately positioned ridges or knurls which will consistently mate with a similarly configured opening in panels to which the floating nut assembly is to be secured.
