Flat Head Head Socket Cap Screws have a clean and unstamped flat head with a countersunk bottom that runs flush with the installation surface. A flat socket cap screw, also known as a flat socket head cap screw, socket screw or Allen flat socket bolt, is a type of cap screw with a cylindrical head and hexagonal drive hole.
Flat Head Head Socket Cap Screws are fully threaded up to the countersink. Head height is measured from the bottom of the countersink to the top of the head. The Black Oxide Treatment to these fasteners adds an additional amount of corrosion and abrasion resistance to the standard 18-8 Stainless Steel. Additionally, this treatment creates a sleek black look to the screws while maintaining the durability of Stainless Steel. Black Oxide 18-8 Stainless Steel is used on black tools, gun builders and car and motorcycles looking for that black sleek look. These fasteners are chemically treated to create the back oxide finish and are finished with wax.
