An all metal, one piece, hex shaped lock nut with a round collar at its back end. The collar is segmented with opposed slots cut into it above each corner of the nut. When the screw or bolt reaches the collar, the slotted portion expands creating the torque locking action. FlexLoc® nuts maintain their locking strength through 15 removals and re-applications, and at temperatures up to 550°F.
