WASHER (Komatsu KO3KB-28-41130)

KO3KB-28-41130: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. The Komatsu catalog reference for this aftermarket replacement part is KO3KB-28-41130. This washer type provides a bearing surface under a fastener head to distribute load. A plain mechanical function 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. This item ships at approximately 0.028 pounds.
