  • Low tolerance threaded fastener
    Publication number: 20070237604
    Abstract: A threaded fastener is having a raised area or bump on a threaded flank. The flank can be positioned on a nut or a bolt thread. The bump forces the mating threads at least on one flank to have near zero tolerance along the pitch line and thereby eliminating play. Also creating an interference which produces friction, thus providing resistance to loosening of thread members.
