The environmentally friendly fine screw electroplating colors include environmentally friendly color zinc, environmentally friendly white zinc, environmentally friendly blue zinc, environmentally friendly black zinc, environmentally friendly nickel, environmentally friendly black zinc and so on. Raw materials: The raw materials of fine screws are iron and stainless steel. The raw materials are stainless steel SUS201, stainless steel SUS304, stainless steel SUS776, stainless steel SUS316, stainless steel SUS404 and so on.
The tail is characterized by sharp tail self-tapping, slotting self-tapping, B-tooth self-tapping, and fast-tooth self-tapping. There are many head shapes of self-tapping fine screws, including pan head, countersunk head, half countersunk head, and the head shape has its own pad and China Sheet Metal Screws without pad. Therefore, the energy screws that require hardness must be hardened. Harden: If the request for fine screws is higher, if there is a request for hardness of fine screws on commodity materials, they usually need to be hardened.
