1/4-20 x 3 1/4 Alloy Steel Socket Head Cap Screw helps maintenance and engineering teams source an alloy steel internal-hex screw with verified head-size data. For production-floor assemblies, the 1/4-20 thread and 3 1/4 in. length help confirm the correct socket cap screw before installation. Industrial buyers may specify it for power transmission, fixture design, and maintenance shops where head geometry and drive access need to be predictable. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 1/4-20 Length: 3 1/4 in.
