Additional information

This flat washer, part number 736-3040, sits between a bolt or nut and the mounting surface to help spread clamping force evenly and reduce surface damage. Proper washer placement helps fasteners stay tight and components remain aligned during operation.

If a fastener loosens repeatedly, digs into the mounting surface, or nearby parts shift out of alignment, a worn, bent, or missing washer may be the cause. Corrosion or deformation can also limit how well the washer distributes load.

Before starting the repair, disconnect the power source appropriate for your equipment to prevent accidental operation. Install the washer in the correct position, then tighten the fastener securely without over-torquing.
