12-24 x 2 1/4 Alloy Steel Socket Head Cap Screw is suited to assemblies that need an alloy steel cap screw for clamp load, service access, and compact installation. For production-floor assemblies, the 12-24 thread and 2 1/4 in. length help confirm the correct socket cap screw before installation. It is frequently used in production lines, automation systems, and tooling when socket engagement is preferred over external-wrench access. 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: 12-24 Length: 2 1/4 in.
