5/8-18 x 2 Alloy Steel Flat Head Socket Cap Screw gives engineers a socket-drive fastener for assemblies where surface projection has to be minimized. Its 82-degree countersunk head is useful when designers want a minimal surface profile while retaining internal hex access for installation and service work.

For fixture construction, machine covers, and production equipment, the 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 5/8-18 thread and 2 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.
