3/8-24 x 7/8 Alloy Steel Button Head Socket Cap Screw is commonly specified when designers need internal-hex access with a broad, finished head profile. The alloy steel construction supports machine construction where the drawing calls for reduced head projection and a socket-drive button head.

It is commonly used on precision assemblies and repair work where buyers can match the listed thread and length to drawings or service records. It is also suited to 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 3/8-24 thread and 7/8 in. length, the reference head diameter is 0.636-0.656 in. and the head height is 0.185-0.199 in. The nominal body diameter and hex-key information below help confirm fit, tool clearance, and replacement requirements.
