Abstract
A screw holding and driving device for use with powered drills including a slidable transparent sleeve mounted in concentric relation with a screw drive shaft of the device. The sleeve is provided with an internal surface that is fluted with the fluted surfaces extending parallel to the longitudinal axis of the cylindrically shaped sleeve. The inner surfaces with larger radii remain clear of the shaft and thus will not be scratched as the shaft moves relative to the sleeve. Further, a split ring of oval construction is provided for holding the sleeve on the shaft. The ends of the split oval retaining ring are sized to fit in a groove on the shaft and thus do not extend outside the groove to scratch the transparent sleeve.
