ABSTRACT:
A nut in combination with a deformable plastic plug is provided so as to produce a torsional reistance when the nut is screwed onto a similar male thread such as a bolt. The plug comprises an inner core wedge and an outer sleeve which will expand upon insertion of the core. The sleeve is placed into the nut, leaving at least one complete turn of the thread free, and the core is wedged into the sleeve forcing it to deform into the thread.
