1/4-28 x 3/4 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 used in machinery repair where a rounded head and socket-drive access help keep service work straightforward.

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.

When checking fit for the 1/4-28 thread and 3/4 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 support counterbore planning, socket access, and replacement matching.
