What is the role of the 4 inch white screw?

When we stayed at the computer for a long time, we need to look at the green plants outside to ease the fatigue of our eyes. On the road, when we saw the red light, we knew we had to stop. Colors have different effects in different places. What is the role of the 4 inch white screw in the hardware industry?

When the customer has an appearance requirement for the item he wants to assemble, the customer’s 4 inch white screw is to coordinate the overall surface color, or it may be for decoration. However, if it is used for appearance parts, then the requirements for the surface are very high, such as no trace on the surface, uniform color, and the like.

When the material of the screw is made of carbon steel, it is usually surface treated on the surface of the screw, otherwise, it is easy to rust, so the 4 inch white screw may be plated with white zinc, which can achieve rust prevention. effect. If it is a Dacromet whose surface is made white, it can not only function as a rust preventive effect but also function as corrosion resistance.
