WASHER - TAB (JCB JC04-800247)

A damaged tab washer can allow fasteners to loosen under vibration, leading to component misalignment or failure. This aftermarket replacement part references JCB catalog number JC04-800247. The tab washer functions as a locking device, using a bent tab to prevent rotation of a nut or bolt. Its plain mechanical role is to secure threaded connections by deforming into a mating slot or flat surface. A common failure consequence is that a missing or worn tab washer permits gradual fastener back-out during operation. The item ships at approximately 0.02 pounds.
