LOCKWASHER (Mitsubishi MB0000-70020)

MB0000-70020: A damaged lockwasher can allow threaded fasteners to loosen under vibration, leading to component separation or misalignment. During assembly, a lockwasher provides spring tension that resists rotational loosening of nuts and bolts. This aftermarket replacement part references Mitsubishi catalog number MB0000-70020. The lockwasher type functions by creating friction between the fastener and the mating surface. A common failure consequence is that a worn or missing lockwasher may result in gradual fastener back-out over time. Keeping a lockwasher in sound condition helps maintain consistent clamping force in bolted joints. Verify the serial number or application, then call (562) 693-7748.
