Abstract
Disclosed is a mechanically lockable fastener assembly for maintaining workpieces assembled, when an elongated bolt with threads formed along a length thereof, and substantially axially aligned rotation resisting surfaces formed along another length thereof, is mechanically assembled with a cooperating nut having a threaded portion and a compressible portion deformable into engagement with said rotation resisting surfaces of said bolt to cause the bolt and the nut of the assembly to be inseparable by untorqued unthreading.
