WASHER - LOCK (Doosan DWA133915)

A worn lock washer can allow fasteners to loosen under vibration, leading to mechanical misalignment or component separation. This aftermarket replacement part references the Doosan catalog number DWA133915. The lock washer type uses a split or toothed design to create tension between a nut and the mating surface. When the washer loses its spring action, the fastener may back out during operation, risking damage to surrounding parts. Keeping a lock washer in sound condition helps maintain consistent clamping force in bolted joints. Verify the serial number or application, then call (562) 693-7748. The part is a hardware washer category item for general fastening applications.
