4-48 x 1 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 is appropriate for tooling applications that require a smooth exposed appearance with internal hex engagement.
This configuration is practical for robotics and packaging machinery where internal hex drive access supports repeatable assembly work in tight spaces. It also works 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 assemblies specified with 4-48 thread and 1 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 maintenance and purchasing teams verify fit and tool access.
Reference dimensions may vary slightly by manufacturer.
