Socket Cap Screws are bolts or machine screws with a Hex or Allen drive style. Knurled Head Socket Cap Screws have an externally grooved cap head and can be driven manually, or with a Hex Allen Bit or Key. A socket cap screw, also known as a socket head cap screw, socket screw or Allen socket bolt, is a type of cap screw with a cylindrical head and hexagonal drive hole. The term socket head cap screw typically refers to a type of threaded fastener whose head diameter is nominally 1.5 times or more that of the screw shank (major) diameter.
Black Oxide Stainless Steel Screws are used in applications looking for a sleek black look, as well as a mild layer of additional protection. Black Oxide Stainless Steel Socket Cap Screws are more corrosion and abrasion resistant than standard 18-8 stainless steel. Black Oxide Stainless Steel is often used in the automotive industry and on tool, knife and firearm builds.
