LOCK NUT - John Blue L-3089

The John Blue L-3089 lock nut is a durable fastening component designed to secure threaded connections effectively. Its all-metal, one-piece, hex-shaped design features a round collar at the back end, segmented with opposed slots. When a screw or bolt reaches the collar, the slotted portion expands, creating a prevailing torque locking action that prevents unintentional loosening due to vibrations and dynamic loads. This design ensures the integrity and reliability of mechanical systems across various applications.
