WASHER (Raymond RA11857-16)

RA11857-16: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references the Raymond catalog and cross-references part number RA11857-16. 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. In a high-vibration environment, a missing or degraded washer may allow the fastener to back out, causing assembly separation. Keeping a washer in sound condition helps maintain consistent preload in threaded connections. Verify the serial number or application, then call (562) 693-7748.
