2-56 x 3/4 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 stockroom identification and purchasing review when counterbored mounting points cannot accept a substitute fastener. The screw is useful across processing equipment, maintenance shops, and industrial automation when a compact internal-hex fastener is required. 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: 2-56 Length: 3/4 in.
