1/4-28 x 3/16 Alloy Steel Socket Head Cap Screw is commonly used where an Allen-style socket drive is preferred over external-wrench hardware in confined equipment layouts. With a 1/4-28 thread and 3/16 in. length, it fits actuated equipment where size interchangeability matters. The screw is useful across production lines, power transmission, and machine tools when a compact internal-hex fastener is required. Verified head dimensions and hex key size help engineering departments check fit before ordering. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 1/4-28 Length: 3/16 in.
