12-28 x 3/4 Alloy Steel Flat Head Socket Cap Screw provides an alloy steel flat head option for machine components designed around countersunk socket screws. Its 82-degree countersunk head is useful when designers want a minimal surface profile while retaining internal hex access for installation and service work.

Common applications include electronics enclosures, access panels, tooling stations, and assembly systems where a smooth exposed face supports safe handling. The material designation gives purchasing teams a clear match for equipment documents that call out alloy steel flat head socket cap screws. The internal hex drive supports top-side socket engagement where side access is limited.

For this 12-28 thread and 3/4 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.
