4-40 x 1 3/4 Brass Socket Head Cap Screw is useful where a size-specific brass socket screw must match existing documentation without changing the material callout. Engineers may specify brass when the assembly benefits from machinable, non-magnetic, or conductive hardware characteristics. Internal-hex engagement gives engineering departments a familiar drive style for brass machine components. Typical placements include machine building, fixture plates, and low-strength locating hardware where brass material properties and socket access are useful. Purchasing agents can source the specified brass fastener without changing the approved product family or material.
