WASHER (Komatsu KO3KA-30-71310)

KO3KA-30-71310: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references the Komatsu catalog number KO3KA-30-71310. The washer provides a bearing surface under a fastener head to distribute load. A plain mechanical function of this type is to prevent galling between the fastener and the mating surface. A concrete generic failure consequence is that a missing or crushed washer can allow the fastener to embed into the part, reducing preload. The item ships at approximately 0.002 pounds. Verify the serial number or application, then call (562) 693-7748.
