1-72 x 1 1/2 Alloy Steel Button Head Socket Cap Screw is commonly specified when designers need internal-hex access with a broad, finished head profile. The alloy steel construction supports machine construction where the drawing calls for reduced head projection and a socket-drive button head.
It is commonly used on robotics and packaging machinery where internal hex drive access supports repeatable assembly work in tight spaces. It is also suited to 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.
When matching the 1-72 thread and 1 1/2 in. length, the reference head diameter is 0.129-0.139 in. and the head height is 0.033-0.039 in. The nominal body diameter and hex-key information below help confirm fit, tool clearance, and replacement requirements.
Reference dimensions may vary slightly by manufacturer.
