Abstract
The threads at the entrance end of a nut are interrupted by a plurality of circumferentially spaced axially extending flutes to form relatively flexible load distributing threads. The flutes extend axially across a limited number of threads and extend radially into the threads a distance short of the root of the thread. After engagement with a complimentary bolt, and upon the occurrence of a load on the connection, the interrupted threads flex axially of the nut to cushion shock on the bolt threads and shift the zone of maximum stress transfer axially inwardly of the nut, thereby materially extending fatigue life of the connection.
