12-24 x 1 1/2 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 is used on industrial equipment where exposed hardware benefits from a rounded head and socket drive.

Frequent uses include robotics and packaging machinery where internal hex drive access supports repeatable assembly work in tight spaces. It is also practical in 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 engineering layouts using 12-24 thread and 1 1/2 in. length, the reference head diameter is 0.383-0.413 in. and the head height is 0.104-0.117 in. The nominal body diameter and hex-key information below keep fit review, tool selection, and replacement ordering tied to verified reference values.
