Flat Head Cap Screws

Flat Head Socket Cap Screws are designed to be seated in countersunk holes, and align flush with the surface of the assembly when installed. Flat head socket cap screws have a flat top surface, an indented hex and a conical bearing surface with a head angle of 82°. Flat head socket cap screws are commonly used in machine parts, die fixturing, and clamping.
