Stainless Steel Screws are fasteners with external threads made from stainless steel through processes such as cold heading, thread rolling, heat treatment, and surface treatment. Their core function is to securely connect two or more components through the engagement of threads with nuts (or pre-threaded holes). They are widely used in construction, machinery manufacturing, electronic equipment, home improvement, automotive, and shipbuilding, and are particularly well-suited for applications requiring corrosion resistance and strength.

Corrosion resistance: This is the key difference between stainless steel screws and carbon steel screws. The chromium element in stainless steel forms a "passivation film" (a dense Cr₂O₃ oxide film) on the surface, preventing oxygen, moisture, and acids and alkalis from coming into contact with the metal, thus preventing rust (carbon steel screws are prone to red rust due to oxidation). This makes stainless steel screws particularly suitable for humid, acidic, and alkaline environments (such as kitchens, bathrooms, outdoor areas, and chemical environments).
