8-36 x 2 3/4 Alloy Steel Button Head Socket Cap Screw helps machine builders secure covers, brackets, and housings while keeping the head smooth and accessible. The alloy steel construction supports manufacturing equipment where a smooth button head and socket engagement are required.

Common installation points include robotics and packaging machinery where internal hex drive access supports repeatable assembly work in tight spaces. It may also be specified for precision assemblies and repair work when buyers can match the listed thread and length to drawings or service records. 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 assemblies specified with 8-36 thread and 2 3/4 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 help maintenance and purchasing teams verify fit and tool access.
