ZINC FLAT & MUDGUARD WASHER IMPERIAL

Zinc-plated imperial flat and mudguard washers are essential fasteners used to distribute pressure and protect surfaces from damage during tightening. While both are flat, they serve distinct purposes based on their surface area and load-spreading capabilities.

Key Differences
Flat Washers (Standard/Commercial): Primarily used to prevent a nut or bolt head from pulling through or damaging the surface of a material. They provide a standard bearing surface.
Mudguard Washers (Fender/Penny Washers): Feature a significantly larger outer diameter (O.D.) relative to the center hole. This extra-wide surface area is ideal for securing thin, soft, or damaged materials and reinforcing oversized or irregular holes.
