3/8-24 x 5/8 Alloy Steel Flat Head Socket Cap Screw is intended for applications where a smooth exposed surface and socket-drive installation are both important. Its 82-degree countersunk head is useful when designers want a minimal surface profile while retaining internal hex access for installation and service work.

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 3/8-24 thread and 5/8 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.
