3-48 x 5/8 Alloy Steel Button Head Socket Cap Screw provides a button-head geometry for assemblies that need a finished appearance and internal hex drive engagement. The alloy steel construction works in maintenance applications where replacement hardware must match the specified button-head geometry.
Engineers may use it on material-handling systems and commercial equipment where the lower rounded profile helps limit snag points. This geometry also fits guards and access panels when maintenance crews can remove covers without extra external wrench clearance. This head style is different from a standard socket head cap screw: it trades the taller cylindrical head form for a rounded button profile used on exposed assemblies.
When checking fit for the 3-48 thread and 5/8 in. length, the reference head diameter is 0.176-0.188 in. and the head height is 0.044-0.052 in. The nominal body diameter and hex-key information below support counterbore planning, socket access, and replacement matching.
Reference dimensions may vary slightly by manufacturer.
