Abstract
A bit holder for holding and driving a screw with a screw head into a fastening base, comprising a clamping region for connecting the bit holder to a driving tool and a bit receptacle for inserting a bit suitable for driving the screw. The bit holder has at least one magnet arranged eccentrically relative to the bit holder with one pole facing the screw head. The at least one magnet is held floating on a magnet holder in relation to a bit held in the bit receptacle, so that the pole face of the magnet can align according to the contour of the screw head in order to hold the screw on the bit holder in such a way that the bit engages torque-locked in a rotary driver contour of the screw head.
