ABSTRACT:
A lock nut has locking members with internal thread segments formed between slots, the segment ends being relieved to prevent galling; also, the members are deformed so that thread segments therein extend along generally circular arcs that have axes offset from the nut axis. Typically, the axes associated with the arcs on said members are at the respective sides of the body axis opposite from said respective members.
