WASHER (CAT CT0358873)

CT0358873: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. Catalog reference CT0358873 is an aftermarket replacement part, cross-referenced to the OE maker CAT. This hardware washer serves as a load-distributing spacer between a fastener head and the mating surface. Its plain mechanical function is to prevent galling and provide a smooth bearing surface for the nut or bolt. In a typical usage context, a missing or degraded washer may allow fastener preload to relax, causing vibration-induced separation. The item ships at approximately 0.05 pounds.
