The Imperial Countersunk Phillips Flat Head Machine Screw is an essential fastening component meticulously designed for precision and durability. Specifically engineered with Unified National Coarse (UNC) or Unified National Fine (UNF) threading, this screw ensures seamless compatibility with equipment and assemblies manufactured to US and UK imperial standards. The countersunk flat head design allows the screw to sit perfectly flush with or below the surface of the surrounding material, resulting in a sleek, professional finish highly sought after in applications where protruding fastener heads could cause interference or aesthetic issues.

This machine screw features a cross-recessed Phillips drive system that significantly enhances torque transmission, minimizing the risk of cam-out. The flat head, angled at 82 degrees per imperial standards, distributes clamping force evenly across the countersink, preventing material distortion. Available in 304/316 Stainless Steel, Carbon Steel with Zinc Plating or Black Oxide, in sizes from #2 up to 3/8-inch and beyond. Indispensable in aerospace, automotive, electronics, metal cabinetry, and precision machinery.
