LOCKWASHER - SPLIT (Mitsubishi MB1037956)

A damaged split lockwasher can allow fastener loosening under vibration, leading to mechanical joint failure. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1037956. The split lockwasher type provides a spring-action grip between a nut and a mating surface. Its plain mechanical function is to resist rotational loosening by exerting axial force. A concrete generic failure consequence is that a worn or missing lockwasher may cause the fastener to back out during operation. Keeping a split lockwasher in sound condition helps maintain consistent clamping force in bolted assemblies. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.01 POUNDS.
