3-48 x 1/8 Alloy Steel Button Head Socket Cap Screw fits applications where engineers want socket drive control in a rounded head rather than an external wrenching feature. The alloy steel construction is appropriate for tooling applications that require a smooth exposed appearance with internal hex engagement.

Frequent uses include production machinery and maintenance repair where socket engagement is practical where side clearance is limited. It is also practical in production machinery and maintenance repair when socket engagement is practical where side clearance is limited. Selection is usually driven by head shape, socket access, and exposed-surface requirements rather than by the geometry of a standard socket head cap screw.

For assemblies specified with 3-48 thread and 1/8 in. length, the reference head diameter is 0.176-0.188 in. and the head height is 0.044-0.052 in. The nominal body diameter and hex-key information below help maintenance and purchasing teams verify fit and tool access.
