WASHER (Komatsu KO012756)

KO012756: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references Komatsu catalog number KO012756. The washer distributes the load of a threaded fastener across a wider surface area. A plain mechanical function of this type is preventing galling between the fastener head and the mating surface. A concrete generic failure consequence is that a missing or crushed washer can allow the fastener to embed into the softer material, reducing preload. During assembly, the correct thickness and hardness of the washer are critical to maintaining torque retention. Verify the serial number or application, then call (562) 693-7748.
