1/2-13 x 3/4 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 precision instruments, test equipment, and panel-mounted hardware 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. Technical Highlights: Material: Brass; Thread: 1/2-13 UNC; Length: 3/4 in.; Nominal Body Diameter: 0.500 in.; Head Diameter: 0.750 in. max / 0.735 in. min; Head Height: 0.500 in. max / 0.492 in. min; Hex Key Size: 3/8; Drive Type: internal hex.
