4-48 x 3/16 Alloy Steel Flat Head Socket Cap Screw is commonly selected when a countersunk hole, clean top surface, and internal hex drive are part of the design. Its 82-degree countersunk head is useful when designers want a minimal surface profile while retaining internal hex access for installation and service work.

Typical uses include machine guarding, equipment covers, fixture plates, and tooling assemblies where a flush fastener helps keep the working surface clear. 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 4-48 thread and 3/16 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.
