Stainless steel fasteners are a type of hardware used to mechanically join or affix two or more components together securely. They are made from stainless steel, a corrosion-resistant alloy that contains iron, chromium, nickel, and other elements. This alloy gives stainless steel fasteners excellent resistance to rust, corrosion, and staining, making them suitable for use in harsh environments and outdoor applications. Stainless steel fasteners come in a wide range of types, including screws, bolts, nuts, washers, threaded rods, and anchors. They are available in various grades and finishes, each offering different levels of corrosion resistance and strength. Common grades of stainless steel used for fasteners include 18-8 (or 304 stainless steel), 316 stainless steel, and 316L stainless steel.
