A screw for securing a wiring element to a terminal cooperates with a screw retainer including resilient nest means for receiving and releasably retaining the screw head. The screw retainer is movable for carrying the screw away from the terminal so that a wiring element with a hole for the screw can readily be moved into and out of mounting position, and for carrying the screw into position ready to be driven into a threaded hole in the terminal when the wiring element is in position to be tightened in place.
