This mudguard washer features an extra-large 40mm outer diameter and is designed for use with M6 bolts or threaded fasteners. Its wide surface area makes it effective at distributing the tightening force over a larger zone, which is especially beneficial when working with soft woods, sheet metal, or thin board materials on site.
Typically used where standard washers might risk deformation or pull-through, the washer's thin profile allows it to be stacked or used in tight spaces. The bright zinc plated finish adds basic protection against corrosion, making it suitable for both interior jobs and covered outdoor applications.
