LOCKWASHER (Doosan DWS5102803)

DWS5102803: A damaged lockwasher can allow threaded fasteners to loosen under vibration, leading to joint failure. This aftermarket replacement part references the Doosan catalog and cross-references part number DWS5102803. A lockwasher is a type of hardware washer that provides a spring-like tension between a nut and the mating surface. Its plain mechanical function is to resist rotational loosening by biting into the fastener and the work surface. A concrete generic failure consequence is that a missing or worn lockwasher can cause a bolted connection to back off over time, risking component separation. The item ships at approximately 0.016 POUNDS. Verify the serial number or application, then call (562) 693-7748.
