ABSTRACT:
A locking nut for use with a bolt for connecting members together. The bolt has a head and a shank. The members are disposed between the head and the nut when the locking nut connects the members together. At least a portion of the shank has external threads formed thereon. The locking nut includes a shell having a bore extending therethrough for receiving the bolt. At least a portion of a wall of the bore has internal threads formed thereon. The shell is sized and shaped to permit rotation of the nut on the bolt for tightening the nut on the bolt. The nut further includes a generally tubular insert sized for being received in the bore of the shell. The insert has a threaded portion having an outer surface with external threads for threaded engagement with the internal threads of the shell, and an inner surface with internal threads for threaded engagement with the external threads of the bolt. The insert includes a locking portion constructed for interlocking the insert with the shell.
