LOCKWASHER (Komatsu KO01602-21242)

KO01602-21242: A worn lockwasher can allow threaded fasteners to loosen under vibration, leading to joint failure. This aftermarket replacement part references the Komatsu catalog number KO01602-21242. A lockwasher is a type of hardware washer that creates tension between a nut and the mating surface. Its plain mechanical function is to resist rotational loosening by biting into both the fastener and the component. A common generic failure consequence is that a missing or collapsed lockwasher may cause the fastener to back off, resulting in component separation or misalignment. During routine service, a lockwasher should be replaced whenever a fastener is removed to ensure continued locking action. Verify the serial number or application, then call (562) 693-7748.
