1/4-28 x 5/16 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 used on industrial equipment where exposed hardware benefits from a rounded head and socket drive.

Frequent uses include machine covers and service panels where the finished head appearance is useful on exposed equipment. It is also practical in control enclosures and equipment housings when the rounded head reduces sharp edges on handled surfaces. The button-head form is specified when the fastener head remains visible or accessible and a smooth rounded profile is preferred.

For engineering layouts using 1/4-28 thread and 5/16 in. length, the reference head diameter is 0.419-0.437 in. and the head height is 0.122-0.132 in. The nominal body diameter and hex-key information below keep fit review, tool selection, and replacement ordering tied to verified reference values.
