ABSTRACT:
A locking threaded fastener of the wedge-action type is disclosed with threaded and threadless nut members with wedge elements therebetween for wedging the nut members apart when the threaded nut member is turned in the loosening direction. In a two-piece nut, the threadless nut member has a flat inner surface for engaging the workpiece and the wedge elements have engaging surfaces with a coefficient of friction therebetween which is less than that between the flat inner surface and the workpiece surface. In a three-piece nut, a third nut member, in the form of a washer, is provided with a flat inner surface for engaging the workpiece. The wedge elements have engaging surfaces with a coefficient of friction less than that between the third nut member and the threadless nut member which, in turn, is less than that between the third nut member in the workpiece.
