5/16-24 x 1 1/2 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. The size callout supports stockroom identification and purchasing review when production-floor assemblies cannot accept a substitute fastener. Industrial buyers may specify it for maintenance shops, assembly equipment, and tooling 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: 5/16-24 Length: 1 1/2 in.
