8-32 x 3/16 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 guards and access panels where maintenance crews can remove covers without extra external wrench clearance. It can also serve automation equipment and conveyor assemblies when the compact head profile helps protect nearby moving components. Unlike a standard socket head cap screw, the button head emphasizes a lower rounded profile and broader exposed head for applications that benefit from that geometry.

When checking fit for the 8-32 thread and 3/16 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.
