Black Oxide Stainless Steel Button Head Socket Cap Screws are chemically treated to add a mild extra layer of corrosion and abrasion resistance as well as a sleek black finished look. Black Oxide Stainless Steel Fasteners are commonly used in industries where the durability of Stainless Steel is required, but a smooth black look is desired. These industries include firearms, automotive (car and motorcycle), camping gear, archery, knife builds and product manufacturing.
