0-80 x 3/4 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 0-80 thread and 3/4 in. length, the reference head diameter is 0.104-0.114 in. and the head height is 0.026-0.032 in. The nominal body diameter and hex-key information below give engineers and buyers a quick check on fit, socket access, and replacement selection.
