1/2-20 x 2 1/2 Alloy Steel Socket Head Cap Screw helps maintenance and engineering teams source an alloy steel internal-hex screw with verified head-size data. The 1/2-20 thread and 2 1/2 in. length support replacement sourcing without changing the specified size in guarding and housings. Applications often include assembly equipment, automation systems, and engineering departments, especially where counterbored or close-clearance mounting 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: 1/2-20 Length: 2 1/2 in. Nominal Body Diameter: .500 in.
