8-36 x 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 is selected for production equipment where a lower-profile head is preferred on exposed fastening points.

Engineers may use it on guards and access panels where maintenance crews can remove covers without extra external wrench clearance. This geometry also fits 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.

For drawings using the 8-36 thread and 1/4 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 fit checks, tool access planning, and replacement verification.
