ABSTRACT:
A lock nut for connecting a joint having a threaded connector has a first nut member which is engageable with a threaded connector and is axially displaceable, a second nut member which is engageable with the first nut member and is rotatable about an axis, a third nut member which is non-rotatably but axially displaceably connected with the first nut member and has a substantially smooth surface over which the second nut member moves during rotation, so that when the second nut member is rotated about the axis against the smooth surface of the third nut member, the first nut member is displaced axially to apply a load to the threaded connector and to tighten the lock nut, and a locking element which non-rotatably connects the first and second nut members with one another after tightening of the lock nut.
