Socket Cap Screw - 5/16-18 x 1-1/2" - Steel Alloy - Thermal Black Oxide - FT - UNC, Pack of 100

Flat Head Socket Cap Screws are used for flush mounting of sections, usually where one part slides over another part or one part is mounted on another. Flat head screws are limited by configuration in their tensile strength capability. Allen/Hex Keys are used to drive the screw.

Socket Head Cap screws are ideal for precision work with close tolerances and applications needing a well tooled appearance. Allen/Hex Keys are used to drive the screw. Socket Head Cap screws supply greater tensile strength than equivalent Hex Head Caps screws, while requiring less surface area to counterbore.

Hex head cap screws have a hexagonal head and are uniformally threaded for use with a corresponding threaded nut or into a threaded tapped hole. Mainly used in repair or construction projects.
