1/4-20 x 2 316 Stainless Steel Button Head Socket Cap Screw helps engineers combine reduced head projection with 316 stainless steel corrosion resistance in equipment that sees moisture or cleaning cycles. The button-head design gives engineers a compact rounded profile, a broad bearing surface, and internal hex drive access, while the 316 stainless steel material is selected where additional corrosion resistance is needed compared with general-purpose stainless grades.

Typical applications include packaging machinery and industrial automation, where reduced head projection helps limit interference near guards, rails, and moving components. It can also serve high-humidity equipment and valve enclosures, where the head geometry keeps exposed hardware smooth while preserving socket access. The button-head geometry is different from a standard socket head cap screw: it keeps a lower, rounded profile while still providing socket engagement.

For the 1/4-20 thread and 2 in. length, the reference head diameter is 0.419-0.437 in. and the head height is 0.122-0.132 in. Use the verified head dimensions below when checking surface projection, socket access, and replacement fit.
