12-28 x 5 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 size callout supports bill-of-material consistency when socket-drive service locations cannot accept a substitute fastener. The screw is useful across manufacturing plants, automation systems, and fixture design when a compact internal-hex fastener is required. Verified head dimensions and hex key size help engineering departments check fit before ordering. The combination of product name, size, material, and verified head data improves search clarity for engineers and buyers. Technical Highlights Material: Alloy Steel Thread: 12-28 Length: 5 1/2 in.
