4-40 x 1 1/2 Brass Socket Head Cap Screw serves maintenance and replacement work when the approved fastener must remain within the brass socket head cap screw family. Brass is often selected for electrical conductivity, non-magnetic properties, machinability, and a clean finished appearance. The cylindrical head gives designers a compact bearing surface while preserving socket drive access for service. Typical placements include processing equipment, maintenance departments, and service brackets where brass material properties and socket access are useful. Industrial distributors can support customers who need a size-specific brass socket head cap screw for repair or production use.
