8-36 x 3 1/2 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 8-36 thread and 3 1/2 in. length, the verified head data helps engineers compare countersink depth, head clearance, and tooling access. Cold Headers helps buyers match thread, length, and head style when replacement hardware must align with existing countersunk components.
