Our specifications for 18-8 stainless steel screws embody M1.0 to M8 and we are able to provide custom manufactured beyond M8 .we take the most advanced technology and machines to ensure screws quality , your satisfaction is always our aim .
Unit : mm
Note : Length of screws are confirmed according standard or your customizaiton .
For a service with long time , self tapping screws are plated in finishing , stainless steel screws can be not plated sometimes .
1 , Zinc
This is popular finish and various colors for choice . The resistance of rust is good and eco-friendly .
2 , Nickel
Nickel finish makes the surface of the screws will more bright and hardened and the performance of screws will be improved .
Most stainless steel screws will be passive after forming so that to stop screws to be rusted .
4 , Tin
It is very perfect to be anti-rust , and widely used to components .
5 , Brass finish
Available for stainless steel screws and carbon steel screws .
6 , Dacromet
Be used for screws with big sizes and can stop screws to be rusted long time even under bad surroundings .
7 , Polishing
Improve roughness of surface .
