1/4-20 x 5/8 Alloy Steel Button Head Socket Cap Screw is used where a rounded, lower-profile head helps keep exposed hardware compact without requiring countersinking. The alloy steel construction is practical for precision assemblies that specify a compact rounded head profile and internal hex drive.
Typical applications include equipment housings and assembly fixtures where the button head presents a clean bearing surface on visible hardware. It also supports 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 1/4-20 thread and 5/8 in. length, the reference head diameter is 0.419-0.437 in. and the head height is 0.122-0.132 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.
