RS PRO Copper Metric Plain Washers
RS PRO range of hard rolled metric copper washers in sizes M3 to M12. This RS PRO range of copper washers are generally used with a machine threaded fastener and nut to spread the load over a greater surface area when tightening a bolt, screw or nut. These washers help prevent wear and distortion of installation surfaces over time whilst reducing heat and friction during the tightening process.
