LOCKWASHER (Mitsubishi MB30020000)

MB30020000: A damaged lockwasher can allow threaded fasteners to loosen under vibration, leading to mechanical misalignment or component separation. During assembly, a lockwasher provides spring tension that resists rotational loosening of a nut or bolt. The aftermarket replacement part cross-references Mitsubishi part number MB30020000. This hardware washer type uses a split or toothed design to create friction against the mating surface. A loose fastener due to a failed lockwasher may cause progressive wear or sudden joint failure in a secured assembly. Keeping a lockwasher in sound condition helps maintain consistent clamping force over time. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.03 pounds.
