What are the plating colors of precision small screws?

After the precision small screw is produced, its surface should be treated. There are professional electroplating manufacturers in the market. The surface of small screws is plated according to the material and customer requirements. For example, the screws made of carbon steel (actually iron) are plated with color. For screws made of stainless steel, a few customers require electroplating color for the consistency of screw and product color. There are several common environmental protection electroplating processes for screws: blue zinc plating, white zinc plating, green zinc plating, black zinc plating, circular nickel plating, same color plating, gold plating and zinc nickel alloy plating. For example, the screws made of stainless steel are cleaned by the electroplating factory, and there is another process called passivation.

Stainless steel screws are also plated with Dacromet. The color is mainly gray, and can also be plated into other colorful colors. In the industry, the color of stainless steel is generally called natural color, and the color of screws is plated according to customer requirements. Customers will also determine the color of precision small screws according to the color of the product.
