Fastener Flatwasher - 7/8

Fastener Flatwasher - 7/8

This 7/8-inch flat washer is a critical fastening component used across various systems on front and rear discharge concrete mixers. It provides a smooth bearing surface that distributes the clamping load of 7/8-inch bolts and nuts, preventing pull-through and protecting the underlying metal surfaces from galling or deformation. Commonly used in high-stress mounting points such as drum roller brackets, pedestal mounts, and heavy structural weldments, this washer ensures secure and lasting assembly. Replacing worn or deformed washers during maintenance is essential to maintain proper bolt tension and prevent equipment failure.
