1/4-20 x 4 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 bill-of-material consistency when production-floor assemblies cannot accept a substitute fastener. Selected for production lines, robotics, and packaging machinery, it gives maintenance teams a searchable alloy steel socket screw callout. Alloy steel supports strength-focused fastening where clamp load and repeatable assembly are important. Those verified dimensions support counterbore checks, tool selection, and replacement fastener review. Technical Highlights Material: Alloy Steel Thread: 1/4-20 Length: 4 3/4 in.
