Fastener Fender Washer 3/8 X 2
Fender Washer · 3/8 inch Bolt
This is a 3/8" x 2" fender washer, a standard but essential piece of hardware for concrete mixer maintenance and assembly. Its primary function is to distribute the clamping force of a nut or bolt head over a much wider area than a standard washer, which is critical when fastening components to thinner materials like sheet metal fenders, guards, or mounting brackets to prevent pull-through or damage. Made from zinc-plated or galvanized steel, it offers corrosion resistance suitable for the harsh, wet environment of concrete work. This type of washer is a general-purpose fastener used across various systems on McNeilus, Terex, and Con-Tech mixers.
