Socket head cap screws are typically used in machine parts, die fixturing, and clamping. Socket head cap screws are ideal for applications in which there is not enough space to maneuver wrenches or sockets.
Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance and to minimize light reflection.
The minimum ultimate tensile strength of the Grade 12.9 Metric Hex Head Bolts is about 1242 Mpa or 180,000 PSI, making them the highest grade of bolts produced.In fact, the Grade 12.9 Nuts is known for their high tensile strength.

Description
Socket Head Cap screws are ideal for precision work with close tolerances and applications needing a well tooled appearance. Socket Head Cap screws supply greater tensile strength than equivalent Hex Head Caps screws, while requiring less surface area to counterbore. Used widely in the home, office and factory appliance, communication equipment's, ship assembly and other machinery industry.
