The Screw is a premium precision hardware product, expertly crafted from high-quality stainless steel for exceptional durability and corrosion resistance. This versatile fastening solution features a meticulously designed helical thread for smooth insertion and superior holding power, making it the ideal choice for a wide range of applications in various industries. Materials and Manufacturing Process of Screws Common materials used for china screw manufacturing include stainless steel, carbon steel, brass, and aluminum. Stainless steel screws offer excellent corrosion resistance, while carbon steel provides high strength. Brass screws are known for their corrosion resistance and electrical conductivity. Aluminum screws are lightweight and often used in applications where weight is a concern. The manufacturing process of screw involves steps such as cold heading, thread rolling, heat treatment, and surface finishing. Cold heading forms the screw head and body, while thread rolling creates the screw threads. Heat treatment enhances the strength and hardness of the bulk screws, and surface finishing may include coating, plating, or passivation to improve corrosion resistance and appearance.
