WASHER (CAT CT19216455)

CT19216455: 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 number CT19216455. 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 torque evenly across the bearing surface. In a typical usage context, a missing or deformed washer may allow the fastener to embed into the mating surface, reducing preload. Verify the serial number or application, then call (562) 693-7748. The part is a hardware washer, a common type used in general assembly applications.
