Abstract

A structure and method for a locknut with a substantially rigid locking member is provided. The locking nut has an elongated body relative to a comparable standard, non-locking nut. The elongated body allows the nut to provide a standard length of thread for engaging bolt members, while also defining a void for the receipt and retention of a removable and replaceable rigid locking member. In a preferred embodiment, the member-carrying void has a forged gear-shaped side-wall structure that substantially engages the locking member within the void while shipping or handling the lock nut, and also causes the member to rotate with the nut as the nut is rotated onto a bolt member, and off of the bolt when loosened. One of either of the bolt threads and locking insert deform responsive to the compressive forces, locking the nut onto the bolt.
