Finishing
Description | Characteristics |
Zinc | Various color can be choosed and perfect on anti-corrosion |
Nickel | Make the surface of the screws more bright and hardened and the performance of screws will be improved |
Polish | Improving the brightness of surface but is inferior is not as zinc in anti-corrosion |
Tin | It is very perfect to be anti-rust , and widely used to components |
Brass | It is usually used with Nickel for more good anti-corrrosion. |
Dacromet | Is used for screws with big sizes and can stop screws to be rusted long time even under bad surroundings . |
