WASHER - LOCK (JCB JC4E-6)

JC4E-6: A damaged lock washer can allow threaded fasteners to loosen under vibration, leading to joint failure. During assembly, the washer's split or toothed design creates spring tension that resists rotation. JCB catalog reference JC4E-6 identifies this aftermarket replacement part. The washer type provides a plain mechanical function by deforming elastically under torque to maintain clamping force. A concrete generic failure consequence is that a missing or worn lock washer may cause bolts to back out, resulting in component separation. Keeping a lock washer in sound condition helps secure connections in applications where movement or shock is present. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.012 POUNDS.
