5/16-24 x 2 1/2 Alloy Steel Button Head Socket Cap Screw supports compact fastening in assemblies where a cylindrical socket head would project farther from the surface. The alloy steel construction fits equipment assemblies where a compact rounded head profile and internal hex drive are specified.
Designers often specify it for brackets, fixtures, and tooling assemblies where the broad head distributes contact over a wider seating area. It can also serve brackets, fixtures, and tooling assemblies when the broad head distributes contact over a wider seating area. Selection is usually driven by head shape, socket access, and exposed-surface requirements rather than by the geometry of a standard socket head cap screw.
For purchasing or maintenance records calling out 5/16-24 thread and 2 1/2 in. length, the reference head diameter is 0.527-0.547 in. and the head height is 0.152-0.166 in. The nominal body diameter and hex-key information below give engineers and buyers a quick check on fit, socket access, and replacement selection.
Reference dimensions may vary slightly by manufacturer.
