ABSTRACT:
A prevailing torque nut in which part of the thread form is truncated to a partial depth to produce interference with a bolt crest engaged therewith. The nut body is thin-walled around the truncated threads such that the body can expand circumferentially to accommodate the larger bolt thread. The expansion is at least partly elastic to permit removal and reuse.
