4-48 x 5/16 Alloy Steel Button Head Socket Cap Screw is selected for socket-drive fastening where head projection, appearance, and bearing area all matter. The alloy steel construction is practical for precision assemblies that specify a compact rounded head profile and internal hex drive.
Suitable assembly locations include equipment housings and assembly fixtures where the button head presents a clean bearing surface on visible hardware. The same head style is useful for 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 4-48 thread and 5/16 in. length, the reference head diameter is 0.201-0.213 in. and the head height is 0.051-0.059 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.
