4-48 x 1 1/2 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 serves automation systems where reduced snag potential and internal hex drive access are useful.
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.
For engineering layouts using 4-48 thread and 1 1/2 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 keep fit review, tool selection, and replacement ordering tied to verified reference values.
Reference dimensions may vary slightly by manufacturer.
