WASHER - FLAT (Mitsubishi MB2I7654)

A worn flat washer can allow fastener loosening under vibration, leading to component misalignment. This aftermarket replacement part references Mitsubishi catalog number MB2I7654. The washer distributes clamping load evenly across a bolted joint surface. Its plain mechanical function is to prevent galling between the fastener head and the mating part. A generic failure consequence is that a missing or crushed washer reduces preload, risking joint separation. During service, a flat washer may also act as a spacer to adjust stack height. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.005 pounds.
