Stainless Steel Flat Head Socket Cap Self-Tapping Screws

Description：

 Material Preparation: The manufacturing process begins with selecting high-quality stainless steel rods, which are cut to the required length based on the screw specifications. The rods are then cleaned and treated to remove any impurities or surface defects, ensuring a smooth and consistent base material for the next steps.

Forming and Threading: The prepared rods are fed into a cold heading machine, where they are forged into the desired flat head shape with an internal hex socket. After forming the head, the screws are transferred to a thread-rolling machine, where self-tapping threads are precisely rolled onto the shank. Finally, the screws undergo heat treatment to enhance their strength and durability, followed by surface finishing processes such as polishing or coating to improve corrosion resistance and appearance.
