Can stainless steel screws be made into a black surface
Sometimes, some customers will ask for the surface color of the screws, because this will increase the aesthetics of their products. So, can stainless steel screws be made into a black surface?

Stainless steel screws can be made into a black surface. If you want to make a black surface, you can generally achieve it through several surface treatments, such as: electrophoresis black, environmentally friendly black zinc, high temperature blackening, vacuum black, etc. Among the electrophoretic black, environmental black zinc, and vacuum black, their blacks are more inclined to jet black. Although they are all black, the color is still different. Electrophoretic black and environmental black zinc are more towards bright black, while vacuum black is more towards matte black. The black that is blackened at high temperature is more like light black.

In terms of price, vacuum black and electrophoretic black are very expensive, then by high-temperature blackening, and lastly, environmentally friendly black zinc, the prices are successively lower. In terms of surface durability, the effect of black zinc is very poor, because the adhesion of this surface is very poor with the surface of stainless steel, and it is very easy to fall off; while the effects of electrophoretic black, high temperature blackening and vacuum black are good performace. , Not so easy to fall off.

What kind of surface treatment is required to make the surface of stainless steel screws black depends on your specific needs.
