3-48 x 3/4 Alloy Steel Flat Head Socket Cap Screw is intended for applications where a smooth exposed surface and socket-drive installation are both important. The flat-head profile is particularly useful around moving stock, operator contact areas, and assemblies where exposed screw heads should not project.

The geometry works well in precision assemblies, panel hardware, inspection covers, and automation cells where clearance around the screw head is limited. Alloy steel construction is appropriate for mechanical fastening applications where the drawing or bill of materials calls for an alloy socket screw. The internal hex drive supports top-side socket engagement where side access is limited.

For this 3-48 thread and 3/4 in. length, the verified head data helps engineers compare countersink depth, head clearance, and tooling access. Cold Headers has supplied specialty socket fasteners since 1962, including flat head sizes used in machine building and repair operations.
