4-40 x 2 1/2 Brass Socket Head Cap Screw helps solve fastening needs in equipment where conductivity, non-magnetic behavior, and clean appearance are more important than clamping load. Compared with alloy steel fasteners, brass is chosen for material behavior such as conductivity and non-magnetic performance rather than structural load capacity. The socket head form works well in counterbored or recessed locations where clean access from above simplifies installation. Typical placements include assembly operations, control enclosures, and commercial equipment where brass material properties and socket access are useful. Assembly operations can standardize this size where conductive or non-magnetic socket-drive hardware is required.
