WASHER (CAT CT301111)

CT301111: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. Catalog reference CT301111 is an aftermarket replacement part, cross-referenced to the OE maker CAT. This hardware washer provides a bearing surface for a fastener and distributes the load evenly. A plain mechanical function of a washer is to prevent galling between the fastener head and the mating surface. A concrete generic failure consequence is that a missing or damaged washer can allow the fastener to embed into the material, reducing preload. During routine disassembly, technicians often find washers that have deformed or corroded. Verify the serial number or application, then call (562) 693-7748.
