RS PRO Plain Stainless Steel Mudguard Washer, M12 x 35 mm, 1.5 mm Thickness


An essential item in any builder or plumber's toolbox, these versatile mudguard washers from RS PRO help to protect surfaces from corrosion and heavy loads by providing a more balanced distribution of weight.

The washer's wide outer ring spreads the load evenly across a bigger surface area. The corrosion-resistant, hardwearing steel material means this product won't degrade or loosen over time. It's suitable to use with an M12 screw or bolt and has a thickness of 1.5 mm.

Another use for these handy washers is to cover holes which may have developed as a result of rust or wear. They comply with RoHS guidelines on the restriction of hazardous substances as well as the Electrostatic Control Standards ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007.

Washers like these are typically found in a range of industries, from the manufacturing and transport sectors to construction.
