WASHER - LOCK M8 (Mitsubishi MB0975372)

A damaged lock washer can allow threaded fasteners to loosen under vibration, leading to component separation. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB0975372. The washer type is a lock washer, which resists rotational loosening by creating a spring-like tension between the fastener head and the mating surface. A common failure consequence is that a missing or worn lock washer may cause the fastener to back out, resulting in misalignment or detachment of secured components. During assembly, the lock washer is typically placed under the fastener head before tightening. The specified size is M8. Verify the serial number or application, then call (562) 693-7748.
