2-56 x 1 1/4 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 machine construction where the drawing calls for reduced head projection and a socket-drive button head.
Common installation points include precision assemblies and repair work where buyers can match the listed thread and length to drawings or service records. It may also be specified for machine covers and service panels when the finished head appearance is useful on exposed equipment. Engineers often choose this style when a standard socket head cap screw would stand taller than the assembly layout allows.
When matching the 2-56 thread and 1 1/4 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 help confirm fit, tool clearance, and replacement requirements.
Reference dimensions may vary slightly by manufacturer.
