ABSTRACT:
A self-locking sheet-metal nut having a generally flat leg with an embossed thread portion for receipt of a screw and a pair of locking tabs resiliently and integrally connected to one end of said leg that extend over and are spaced from the leg. The tabs are approximately perpendicular to the axis of the screw and have clamping edges which are directed toward each other and form an opening downstream of the embossed thread portion that is smaller than the core diameter of the screw to be threaded into the nut. Upon turning of a screw through the nut, the clamping edges are forced apart and resiliently grip the core of the screw to lock it in place.
