Mr. Hu wants a truss head screw that can conduct electricity. According to Mr. Hu’s request, Shishi recommended Hu to use copper material. Mr. Hu said that copper can be used, but he wants  brass  truss head screws . Brass-based Shishitong can also be produced, so you can. Then Mr. Hu gave his drawings to Shishitong. After reading Mr. Hu’s  brass truss head screws  drawings, we suggested that Mr. Hu change the depth of the inner plum blossoms to a lighter one.

Recently, a customer asked for a  truss head screws  stainless when ordering, but the surface treatment wanted to make bismuth zinc. When customers say this, we generally advise customers not to do bismuth zinc. Why is this? Generally, the surface treatment of the screws is to make the screws less likely to rust.

Because the adhesion of stainless steel to zinc is not very strong, even if it is made, it is easy to fall off when it is used, that is, it is white. For example, take a stainless steel large flat head screw with an environmentally friendly zinc-plated surface and apply a little force on the paper. The plating on the surface of the screw is easy to drop, and the mark can be clearly seen on the paper. If you really want black surface treatment, it is usually anodized...
