ABSTRACT:
A shaft having a pair of oppositely angled projections on one end engages the head of a one-way screw for retracting the screw by rotation of the shaft. The shaft may integrally carry a stabilizing blade provided with said projections and assist in holding them in place against the screw head while the shaft is struck with a hammer to drive the projections into the screw head. A handle may be attached to the shaft, but the end of the shaft extends through the handle to be exposed so that the shaft may be struck by the hammer.
