ABSTRACT:
A self-locking connection between a bolt and a nut is obtained by making at least one face of at least one flight of the external thread of the bolt and/or the internal thread of the nut incongruous with the adjacent face of the other thread. This results in a clamping action along a helix at the root and/or at the crest of the other thread. The connection is self-locking in two directions if both faces of one or more flights of one of the threads are incongruous with the adjacent faces of the other thread.
