摘要： A combined screw driving and screw gripping tool with which a screw, being attached to the tool, can be moved towards and away from a screw hole without fear of being accidently dislodged from the tool. The screw driving portion of the tool is provided with at least one resilient tongue like element which extends in the longitudinal direction of the tool and which, when inserted in the tool receiving cavity of a screw or the like, exerts a spring force of such magnitude against its contacting surface of the cavity that the screw is held on the tool against accidental dislodgement therefrom.
