12-24 x 2 1/4 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 equipment housings and assembly fixtures where the button head presents a clean bearing surface on visible hardware. It can also serve material-handling systems and commercial equipment when the lower rounded profile helps limit snag points. The button-head form is specified when the fastener head remains visible or accessible and a smooth rounded profile is preferred.

For purchasing or maintenance records calling out 12-24 thread and 2 1/4 in. length, the reference head diameter is 0.383-0.413 in. and the head height is 0.104-0.117 in. The nominal body diameter and hex-key information below give engineers and buyers a quick check on fit, socket access, and replacement selection.
