Socket head cap screws offer higher tensile strength compared to hex head cap screws while requiring less surface area, similar to countersunk screws. These screws are commonly referred to as Allen bolts or Allen head screws. The head is designed to be embedded into the material, providing a stronger connection. They are ideal for precision work where tight tolerances are required and for applications that demand a clean, professional appearance.
Typical materials used include Alloy Steel, Stainless Steel, and Carbon Steel. The strength of the screw is indicated by markings on the head, which follow the relevant industry standards.
