0-80 x 5/16 Alloy Steel Flat Head Socket Cap Screw supports flush-mounted fastening in equipment where raised hardware could interfere with covers or moving parts. 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 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 5/16 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.
