These stainless steel washers from RS PRO can be used in all types of fastener assembly, where they extend joint lifetime by reducing wear and tear caused by friction. By insulating steel fasteners away from aluminium surfaces, washers can significantly help to prevent galvanic corrosion.

Washers are commonly used in a wide range of settings including chemical, food and electronic applications, where they contribute towards an even load distribution and reduce pressure. Not only do they stop mating surfaces from becoming distorted over time, they also allow for smoother loosening and tightening of components, which makes maintenance easier.

These plain washers are suitable for use with M12 size screws and bolts. They are made from high quality A2 304 stainless steel, which is particularly hardwearing and corrosion resistant.

Like all products in the RS PRO range, these washers have been exhaustively tested for reliability and safety.
