Metric Socket Flat Head Screw / Bolt
Metric socket flat head screws are threaded fasteners that are tapered under the head and are commonly used in a countersunk hole application so that the head of the screw sits flush with the surface. Socket flat head screws have an inner hex drive and require a hex key to turn and tighten.
