LOCK WASHER - SPLIT 1/2 INCH (Komatsu KO01601-01236)

A damaged lock washer can allow bolted joints to loosen under vibration, leading to fastener failure. During assembly, a split lock washer provides spring tension that resists rotational loosening. The aftermarket replacement part cross-references Komatsu part number KO01601-01236. This split lock washer is sized at 1/2 INCH. Its split design creates a spring action that maintains clamping force. A common failure consequence is that a missing or worn lock washer can cause the fastener to back out, resulting in component separation. Verify the serial number or application, then call (562) 693-7748.
