The connector tool apparatus includes a handle assembly integral with an actuator assembly. The handle assembly includes a main body resembling a screw driver handle connected to a clip connector assembly. The clip connector assembly includes a connector coupling having a central threaded hole to receive a threaded shaft of the hanger clip therein during use thereof. The actuator assembly includes a U-shaped connector arm with parallel arm sections, each integral with a connector head of conical shape. The connector heads cooperate to rotate a connector nut of the hanger clip during assembly thereof.
