WASHER - FLAT (Mitsubishi MB2I8180)

A damaged flat washer can allow fastener loosening under vibration, leading to joint failure. During assembly, a flat washer distributes clamping load over a wider surface area. This aftermarket replacement part references Mitsubishi catalog number MB2I8180. The washer's plain mechanical function is to reduce friction between the fastener head and the mating surface. A common consequence of a missing or worn washer is galling or surface deformation on the fastened component. Keeping a flat washer in sound condition helps maintain consistent torque retention over time. Verify the serial number or application, then call (562) 693-7748.
