WASHER - LOCK (JCB JC332/G5343)

A damaged lock washer can allow fastened components to loosen under vibration, leading to misalignment or mechanical failure. During assembly, a lock washer resists rotational loosening by embedding its edges into the mating surface. The JCB catalog reference for this part is JC332/G5343, and it is an aftermarket replacement part. This washer type provides a plain mechanical function of creating tension between a fastener and the work surface. A common generic failure consequence is that a missing or worn lock washer may cause a nut to back off, resulting in lost clamping force. Keeping a lock washer in sound condition helps maintain joint integrity in fastened assemblies. Verify the serial number or application, then call (562) 693-7748.
