12-24 x 1 1/4 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 brackets, fixtures, and tooling assemblies where the broad head distributes contact over a wider seating area. This geometry also fits brackets, fixtures, and tooling assemblies when the broad head distributes contact over a wider seating area. Selection is usually driven by head shape, socket access, and exposed-surface requirements rather than by the geometry of a standard socket head cap screw.

When checking fit for the 12-24 thread and 1 1/4 in. length, the reference head diameter is 0.383-0.413 in. and the head height is 0.104-0.117 in. The nominal body diameter and hex-key information below support counterbore planning, socket access, and replacement matching.
