Material - Constructed with carbon steel material with blackening treatment, the hex socket cap screw is of stronger durability, has a bright appearance, is not easier to deform or corrode, and has a long service life than other surface finishes.

Feature - The button socket head cap screw is designed with an inner hex drive style and pan head, providing a higher torque and clamping force, as well as offering a wider bearing surface and high tensile strength.

Application - Good replacement parts and construction fasteners for use in most machinery industries, automotive industries, electronics industries, manufacturing applications, die fixtures, and clamps.

Installation - To access this hex drive screw, you will need to use a hex wrench to tighten or loosen. The socket button head design enhances torque capabilities, allowing for greater clamping force. For optimal results, it is recommended to use a retaining washer to securely lock the hex drive in place.
