1/2-13 x 11 Alloy Steel Socket Head Cap Screw is specified when a machine assembly needs a high-strength alloy steel socket screw with predictable head and drive geometry. With a 1/2-13 thread and 11 in. length, it fits high-clamping-force joints where size interchangeability matters. The screw is useful across fixture design, tooling, and robotics when a compact internal-hex fastener is required. The dimensional highlights make the listing more useful for maintenance shops and industrial distribution teams. This keeps the listing focused on the fastener geometry rather than broad catalog language. Technical Highlights Material: Alloy Steel Thread: 1/2-13 Length: 11 in. Nominal Body Diameter: .500 in.
