Function Flat washers distribute the load from threaded bolts, screws, and nuts, creating a smooth bearing surface that protects mating surfaces. Material Copper washers offer corrosion resistance and electrical conductivity. Applications Suitable for electrical connections and use across sectors including household and commercial appliances, automotive and marine industries, fuel systems, and hydraulic installations. Easy to use Installation is straightforward; the smooth washer surface reduces friction between the screw and nut, helps prevent leakage, isolates, and prevents loosening or uneven pressure. Size and compatibility Designed for standard bolt and nut sizes. Available in copper washer sizes to match common hardware. Use scenarios Electrical connections in automotive and marine electrical systems to ensure reliable conductivity and corrosion resistance. Sealing and spacing in fuel system fittings to reduce leakage and protect joints. Providing a durable bearing surface in hydraulic equipment and general machinery to distribute load and prevent wear.
