Copper Sealing Washers, M4

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.
