Material
Brass screws are made of alloy brass with model No. CuZn37 for electronics , they are also made of in Brass CuZn35 , CuZn40 , CuZn37Pb1 and CuZn39Pb1
Features
Perfect conduction
Brass screws are a good choice for assembly in electronics components that need transmit of power from one part to another part .
Wear resistant
Brass screws with good elongation and not easy to be slipped when they are assembled .
Durable corrosion
Do not need extra finish or surface treatment for corrosion , they are good at stopping corrosion .
Resistant heat
Brass screws can be workable even temperature is over 200°.
Bright appearance
Brass screws are not be reacted with other chemicals , and the performance on corrosion proof and roughness are more good after nickel plated .

Optional Surface Finish
Generally , brass screws are not needed to be plated , but for more longer service or high request on roughness , brass screws can be plated as following finish .
1 , Zinc
Most popular finish and various colors for choice . The resistance of rust is good and eco-friendly .
2 , Nickel
Make the surface of the screws more bright and harden and the performance of screws will be improved .
3 , Tin
Very perfect to be anti-rust , and widely used to electronic components .
4 , Chrome
Harden surface ,Bright surface ,Heat resistance ,Wear resistance Corrosion resistance and eco-friendly
