WASHER - LOCK (Bobcat BC64633.1)

A damaged lock washer can allow bolted connections to loosen under vibration, leading to component misalignment or failure. This aftermarket replacement part references Bobcat as the OE maker and cross-references part number BC64633.1. The washer type provides a locking function by creating tension between the fastener and the mating surface. A plain mechanical function is that the washer deforms slightly during tightening to resist rotational loosening. A concrete generic failure consequence is that a missing or worn lock washer may cause the fastener to back out, resulting in mechanical noise or detachment. The item ships at approximately 0.012 pounds. Verify the serial number or application, then call (562) 693-7748.
