Finish
| Finish | description |
| 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 | Very perfect to be anti-rust , and widely used to components |
| Brass | It is usually used with Nickel for more good anti-corrrosion. |
| Paint | Its powder paint with colors to prevent surface from rust. |
| Oxide | Oxide is often black color |
