0-80 x 1 1/4 Alloy Steel Flat Head Socket Cap Screw supports flush-mounted fastening in equipment where raised hardware could interfere with covers or moving parts. The flat-head profile is particularly useful around moving stock, operator contact areas, and assemblies where exposed screw heads should not project.

The design is well suited to inspection fixtures, machine frames, material-handling equipment, and repair work that calls for a countersunk internal-hex screw. 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 0-80 thread and 1 1/4 in. length, the verified head data helps engineers compare countersink depth, head clearance, and tooling access. Cold Headers supports exact-size sourcing for specialty socket products and uncommon lengths used in industrial maintenance and production work.
