RS PRO Plain Stainless Steel Mudguard Washer, M10 x 30 mm, 1.5 mm Thickness


Use this mudguard washer from RS PRO when installing a bolt or screw into an oversized hole. It's made of corrosion-resistant A4 316 stainless steel, so it's suitable for use in a wide range of demanding environments.

The washer has a diameter coverage area of 30 mm, so it evenly distributes loads and covers excess space for a more secure fixing. There's no need to worry about denting or damage to your surfaces, as the tough steel material is thick enough to resist tightly screwed nuts.

The mudguard washer has a 10.5 mm internal hole diameter, making it suitable for use with M10 fittings or screws. This type of washer is used for a wide range of purposes, from boat and bicycle repair to fabricating roofs.
