Abstract: A method for making a lock nut engagable and retainable about a threaded shaft wherein a body member having a bore is threaded for receiving a threaded shaft, and at least a portion of the bore is deformed to provide threaded shaft engaging means engagable with a threaded shaft disposed in the bore. The deformed portion of the bore is then sized with a threaded sizing tool that is oversized relative to the deformed portion of the bore and undersized relative to any undeformed portion of the bore to provide a sized lock nut with a relatively consistent torque performance and a reduced statistical spread over several installation and removal cycles of the nut about the threaded shaft.

Abstract: A lock nut having a body member with a threaded axial bore and a washer having an axial opening coupled to a bottom end portion thereof so that the opening of the washer is aligned substantially with the threaded axial bore. The washer has one or more fingers with threaded finger tip portions partially defining the opening thereof. The threaded finger tip portions of the washer are in-phase helically with the threaded axial bore of the body member. A recess is disposed between the washer and the body member, and a protruding portion of the washer extends from the bottom end portion of the body member.
