Abstract
A screwdriver is disclosed having a shaft with a screw holder. The screw holder is receivable in a recess in a screw head, and has a spring element which can be elastically deformed transverse to the longitudinal axis of the shaft. A portion of the spring element may be engaged with a bore in the shaft and the bore may penetrate the front end of the shaft. The elastic segment may be disposed in a groove parallel to the longitudinal axis of the shaft segment so that, in the unstressed state of the spring element, at least a portion of the elastic segment protrudes beyond the cross-sectional surface of the shaft segment to engage a surface of the screw head recess to thereby retain the screw on the shaft.
