1 1/4-7 x 7 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 1/4-7 thread and 7 in. length support bill-of-material consistency in high-clamping-force joints. It is frequently used in power transmission, processing equipment, and machine tools when socket engagement is preferred over external-wrench access. 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: 1 1/4-7 Length: 7 in.
