Flat copper washers Function and compatibility Distributes the load from threaded bolts, screws, and nuts to create a smooth bearing surface and improve joint stability. Designed to fit standard fasteners for reliable, consistent performance in fastening applications. Material and performance Copper construction provides corrosion resistance and electrical conductivity. Suitable for applications where a durable, conductive bearing surface is required, including environments with vibration or temperature variation. Applications Widely used in electrical connections across diverse sectors, including household and commercial appliances. Common in automotive and marine installations, fuel systems, and hydraulic fittings where corrosion resistance and conductivity are important. Easy to use Smooth washer surfaces reduce friction during installation, help prevent leakage, provide isolation, and resist loosening or uneven pressure distribution. Use scenarios Electrical panel wiring and control cabinet connections in residential or commercial settings. Automotive engine bay and marine electrical connections, including fuel system and hydraulic line fittings. Household appliances and power tools requiring reliable electrical contact and corrosion resistance.
