12-24 x 2 1/2 Alloy Steel Flat Head Socket Cap Screw gives engineers a socket-drive fastener for assemblies where surface projection has to be minimized. The flat-head profile is particularly useful around moving stock, operator contact areas, and assemblies where exposed screw heads should not project.

For fixture construction, machine covers, and production equipment, the 82-degree countersunk head helps avoid raised fastener edges without requiring external wrenching space. As an alloy steel socket fastener, it is selected for industrial assemblies that require a durable internal-hex screw where countersunk geometry and socket-drive access are important. The internal hex drive supports top-side socket engagement where side access is limited.

For this 12-24 thread and 2 1/2 in. length, the verified head data helps engineers compare countersink depth, head clearance, and tooling access. Cold Headers focuses on difficult-to-find socket products where exact thread, length, and head style matter to the application.
