RS PRO Plain Stainless Steel Mudguard Washer, M6 x 30 mm, 1.5 mm Thickness


If you're installing a screw or bolt into an oversized hole, try this RS PRO plain steel mudguard washer. It covers the excess space and prevents a loss of tautness to your fastening.

The A4 316 stainless steel body material is high strength and keeps the mudguard shiny and free of dents over time. Its 1.5 mm thickness keeps the fitting secure and protects your surfaces as the washer has the strength to resist having strong nuts screwed tightly against it.

The mudguard washer has a 30 mm diameter coverage area to ensure the full excess of a fixing is covered. Its internal hole diameter is 6.4 mm, making it ideal for use with M6 screws or bolt fittings.
