WASHER - LOCK M8 (Doosan DWMF450405)

A worn lock washer can allow a fastener to loosen under vibration, leading to component misalignment or detachment. This aftermarket replacement part references the Doosan catalog number DWMF450405. The washer is a lock type, sized M8, which provides a plain mechanical function of preventing rotational loosening. A concrete generic failure consequence is that a missing or crushed lock washer may cause a bolted joint to back out during operation. Keeping a lock washer in sound condition helps maintain clamping force on the fastener. Verify the serial number or application, then call (562) 693-7748.
