WASHER (JCB JC04-801677)

A damaged washer can allow fastener loosening, leading to component misalignment or failure. During inspection, a washer distributes load and prevents galling between a fastener head and the mating surface. The aftermarket replacement part references JCB as the OE maker and cross-references part number JC04-801677. This hardware washer type provides a plain mechanical function of reducing surface friction under torque. A concrete generic failure consequence is that a missing or worn washer may cause fastener pull-through or joint separation. Keeping a washer in sound condition helps maintain clamping force in assembled joints. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.002 pounds.
