Copper nut is defined as a nut made of copper material (usually leaded brass, such as H59,H62). The copper nut we come into contact with is mainly hexagon nut or other copper nut matched with the bolt.
Copper nut is not easy to rust, corrosion resistance, easy thermal conductivity and strong electrical conductivity and other advantages, generally used in rust prevention, high temperature, conductive, heat conduction and other use environment, such as faucet, valve, electrical switch.
