ABSTRACT:
A rotation resistant nut having an internally threaded nut body and having a portion of the exterior surface of the nut body provided with an irregular configuration. The rotation resistant nut is adapted to be used as an insert-type nut and upon installation of the nut into a round hole in a workpiece having a diameter smaller than the major diameter of the nut, the workpiece deforms the nut body so that the internal threads of the nut become distorted to create a prevailing torque locking characteristic between the internal threads of the nut and a cooperating threaded male fastener.
