8-36 x 3/8 Alloy Steel Socket Head Cap Screw provides a strength-focused alloy steel socket cap screw option for mechanical assemblies requiring this exact size. The size callout supports repair work tied to an existing fastener callout when counterbored mounting points cannot accept a substitute fastener. Industrial buyers may specify it for production lines, engineering departments, and power transmission where head geometry and drive access need to be predictable. Verified head dimensions and hex key size help engineering departments check fit before ordering. The result is a clear alloy steel socket head cap screw listing for purchasing review and procurement. Technical Highlights Material: Alloy Steel Thread: 8-36 Length: 3/8 in.
