1/4-20 x 2 1/4 Brass Socket Head Cap Screw is specified where a non-ferrous internal-hex fastener is preferred for electrical assemblies or precision hardware. The non-ferrous construction can be useful near electrical components, test fixtures, controls, and instruments. The internal hex drive supports positive tool engagement where surrounding components limit outside wrench clearance. Typical placements include laboratory equipment, instrument housings, and electrical enclosures where brass material properties and socket access are useful. Design engineers can compare the listed head dimensions and hex key size against counterbore and tool-access requirements.
