4-48 x 1/4 Alloy Steel Button Head Socket Cap Screw gives equipment builders a rounded button-head form for visible or frequently handled fastening points. The alloy steel construction fits fixture construction where a broader bearing surface and socket-drive access are part of the design.
This configuration is practical for precision assemblies and repair work where buyers can match the listed thread and length to drawings or service records. It also works in 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 4-48 thread and 1/4 in. length, the reference head diameter is 0.201-0.213 in. and the head height is 0.051-0.059 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.
