1/2-13 x 1 1/4 Brass Socket Head Cap Screw provides a brass socket-drive option for compact assemblies that need hex-key installation and material compatibility. The brass material is appropriate for compatible low-strength joints where conductivity and appearance are design considerations. Hex-key installation helps technicians reach fastening points inside covers, panels, brackets, fixtures, and housings. Typical placements include commercial hardware, display fixtures, and access panels where brass material properties and socket access are useful. Engineering departments can evaluate head clearance, drive access, and brass material compatibility before releasing the assembly.
