2-56 x 1/2 Alloy Steel Button Head Socket Cap Screw is used where a rounded, lower-profile head helps keep exposed hardware compact without requiring countersinking. The alloy steel construction is practical for precision assemblies that specify a compact rounded head profile and internal hex drive.
Typical applications include automation equipment and conveyor assemblies where the compact head profile helps protect nearby moving components. It also supports equipment housings and assembly fixtures when the button head presents a clean bearing surface on visible hardware. Engineers often choose this style when a standard socket head cap screw would stand taller than the assembly layout allows.
For purchasing or maintenance records calling out 2-56 thread and 1/2 in. length, the reference head diameter is 0.154-0.164 in. and the head height is 0.038-0.046 in. The nominal body diameter and hex-key information below give engineers and buyers a quick check on fit, socket access, and replacement selection.
Reference dimensions may vary slightly by manufacturer.
