8-36 x 1/2 Alloy Steel Button Head Socket Cap Screw supports compact fastening in assemblies where a cylindrical socket head would project farther from the surface. The alloy steel construction works in maintenance applications where replacement hardware must match the specified button-head geometry.

Designers often specify it for brackets, fixtures, and tooling assemblies where the broad head distributes contact over a wider seating area. It can also serve 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 8-36 thread and 1/2 in. length, the reference head diameter is 0.298-0.312 in. and the head height is 0.077-0.087 in. The nominal body diameter and hex-key information below support counterbore planning, socket access, and replacement matching.
