ABSTRACT:
This invention relates to fasteners and more particularly to a male or female fastener element, such as a bolt or nut, having a skewed external work contacting surface such that when the fastener element is tightened onto another fastener element, and against a workpiece, a substantial lateral loading is produced. Such loading causes the male and female threads to shift laterally into an asymmetric, jammed configuration which has been found to exhibit extraordinary resistance to loosening under conditions of vibration. The nut thread is characterized by a helical flat at the major diameter thereof to make positive contact with the crown of the bolt thread when lateral skewing occurs.
