ABSTRACT:
A vibration-resistant prevailing torque fastener combination comprising a conventional first element having a standard thread form with first flank angles and a modified second element having a thread form characterized by second steeper flank angles over the entire length thereof, and a truncated root caused by foreshortening of the flanks over a portion of the thread length to produce a helical flat which firmly engages and typically deforms the crest of the first element when threadedly engaged therewith. A difference in flank angles provides longitudinal clearance to receive the deformed material during the threaded engagement. Tapping tools are disclosed.
