【Material】- Flat Washers are made of Red Copper without surface treatment, which with high conductivity, corrosion resistant. They have a tighter seal and high heat resistance than steel and rubber washers
【ADVANTAGE】- They are very easy to install, the washer's surface are smooth can reduces friction between the screw and nut, prevents leakage, isolates, prevents loosening or dispersion pressure
【APPLICATION】- High quality copper flat washers with high conductivity perfect for electrical connections on household and commercial appliances, automotive and marine uses in which the power source has a threaded/bolt-type connection
