Button Head Socket Cap Screws - Black Oxide Stainless Steel

Screw Diameter - Thread Pitch: #4-40

Button Head Socket Cap Screws are bolts or machine screws with a Hex or Allen drive style. Button Head Socket Cap Screws have a clean and unstamped domed head with a flat bottom that protrudes above the installation surface for a nice finished look. A Button Socket Cap Screw, also known as a Button Socket Head Cap Screw, Socket Screw or Allen Button Socket Bolt, is a type of cap screw with a cylindrical head and hexagonal drive hole. The term Button Head Socket 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 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.
