NUT - 3/8 LOCK PLASTIC (Bobcat BC81D000006)

BC81D000006: A damaged lock nut can compromise the security of a bolted joint, leading to loosening under vibration. During assembly, a 3/8 lock nut with a plastic insert resists backing off by creating friction on the threads. This aftermarket replacement part references the Bobcat catalog number BC81D000006. The plastic locking element deforms slightly when tightened, providing a prevailing torque that holds the nut in place. If the locking feature fails, the nut may loosen over time, causing fastener failure in a bolted connection. Keeping a lock nut in sound condition helps maintain clamp load in threaded assemblies. Verify the serial number or application, then call (562) 693-7748.
