Title: Screw Manufacturing and Surface Treatment Techniques
Article: Screws are a common type of fastener used to secure objects or parts together. The manufacturing process of screws is complex and requires precise techniques and high-quality materials. Screws are typically made of carbon steel, stainless steel, or alloy steel, each with different hardness and lifespan. The manufacturing process of screws involves material selection, design of specifications and dimensions, as well as threading and hole machining. To enhance the durability and safety of screws, they are often subjected to heat treatment and surface treatment, such as nickel plating or copper plating, to prevent corrosion and improve surface hardness.
