RS PRO Plain Stainless Steel Mudguard Washer, M8 x 30 mm, 1.5 mm Thickness


Installing a bolt or screw and want to make sure the load is evenly distributed? Use this RS PRO mudguard washer. It's made of A4 316 stainless steel, so it's highly corrosion-resistant. This makes it suitable for use in marine environments. The material is also tough, so it will remain shiny and dent-free for a long time. Its thickness of 1.5 mm means it won't easily deform, so you can count on it to protect your surfaces from tightly screwed nuts.

The mudguard washer has an 8.4 mm internal hole diameter, so it's suitable for use with M8 bolts or screw fittings. Its outside diameter of 30 mm fully covers the excess of a fixing.
