WASHER (CAT CT1177361)

A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references the CAT catalog and carries the part number CT1177361. The washer functions as a load-distributing spacer placed under a fastener head or nut. Its primary mechanical role is to prevent galling and distribute tightening torque evenly across the mating surface. A common failure consequence is that a crushed or missing washer allows the fastener to embed into the softer material, reducing preload. Verify the serial number or application, then call (562) 693-7748. The part is a hardware washer, a generic type used in many mechanical assemblies.
