Shoulder Socket Head Cap Screw with Black Oxide Plating
A black oxide socket head shoulder cap screw is a type of fastener that combines the design features of a socket head cap screw with a black oxide coating. The socket head provides a hexagonal recess in the screw's head, allowing for easy installation and removal with an Allen wrench or hex key. The shoulder of the screw is a smooth, cylindrical section that provides a bearing surface, making the screw ideal for applications that require load distribution, precise alignment, or pivoting actions between parts.
The black oxide coating is a chemical conversion process that creates a thin, protective layer on the surface of the metal. It offers several benefits, including enhanced corrosion resistance, a sleek black finish, and improved wear resistance. This coating does not alter the dimensions of the screw significantly, making it ideal for applications where tight tolerances are crucial. The black oxide layer also reduces light reflection, which is beneficial in certain industries like aerospace and military applications, where appearance and stealth are important.
Black oxide socket head shoulder cap screws are typically made from materials such as alloy steel, providing excellent strength and durability. The shoulder provides support in the assembly, and its smooth surface helps ensure that the fastener doesn't damage or deform the parts it is securing. These fasteners are particularly well-suited for applications involving mechanical parts like motors, fixtures, and structural components that experience both shear and axial loads.
The combination of the socket head design with the black oxide finish makes these screws popular in industries such as automotive, aerospace, robotics, and manufacturing, where reliability, precision, and corrosion resistance are crucial.
