8-36 x 5/16 Alloy Steel Button Head Socket Cap Screw fits applications where engineers want socket drive control in a rounded head rather than an external wrenching feature. The alloy steel construction fits fixture construction where a broader bearing surface and socket-drive access are part of the design.

Frequent uses include control enclosures and equipment housings where the rounded head reduces sharp edges on handled surfaces. It is also practical in robotics and packaging machinery when internal hex drive access supports repeatable assembly work in tight spaces. 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 matching the 8-36 thread and 5/16 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 help confirm fit, tool clearance, and replacement requirements.
