    Countersunk socket screws, also known as flat head or simply flat socket head cap screws, are designed for use in applications where the head cannot protrude above the mating parts. They are set in 90° countersunk holes and the top of the head sits flush or slightly below the surface of the assembly.

    Dimensions are indicative only. Confirmation prior to ordering is advised if any of these dimensions are of critical importance to your application.
