Stainless steel screws refer to standardized mechanical parts made of stainless steel (alloy steel with a chromium content ≥ 10.5% and a carbon content ≤ 1.2%, and some containing elements such as nickel and molybdenum). They have the core function of "fastening connection" and are corrosion-resistant, rust-proof, and have certain mechanical strength and environmental adaptability. They are widely used in construction, machinery, electronics, home appliances, automobiles, ships, medical equipment and other fields. They are used to fix two or more components (such as metal parts, plastic parts, stone parts) into a whole, or to achieve detachable assembly of parts.

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).
