WASHER (Mitsubishi MB1017148)

A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references Mitsubishi as the OE maker and carries the cross-reference part number MB1017148. The washer acts as a load-distributing spacer placed under a fastener head or nut. Its plain mechanical function is to prevent galling and distribute the fastener's load evenly across the surface. A common failure consequence is that a crushed or missing washer allows the fastener to embed into the material, reducing preload. During reassembly, always inspect the washer for deformation or cracking. Verify the serial number or application, then call (562) 693-7748.
