WASHER (JCB JC445-10803)

A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references JCB as the OE maker and cross-references part number JC445-10803. The washer functions as a load-distributing spacer placed under a fastener head or nut. Its plain mechanical role is to prevent galling and distribute torque evenly across the mating surface. A generic failure consequence is that a missing or deformed washer may allow fastener preload to drop, risking joint separation. The item ships at approximately 0.044 pounds. Verify the serial number or application, then call (562) 693-7748.
