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.

A hand-held tool comprises a tool part and a handle surrounding a section of the tool part and connected to same in a torque-transmitting manner. The tool part comprises a connection contour used to connect the handle in a torque-transmitting manner at least in some areas, in a section surrounded by the handle. The handle comprises an inner handle piece which can be connected to the connection contour and surrounds same in a torque-transmitting manner. With the inner handle piece slid onto the connection contour, one or more outwardly-open casting channels are provided between the two parts. The handle further comprises an outer handle piece made of plastic, which during the course of a plastic moulding process is moulded around the unit comprising the tool part which has an inner handle piece connected to the connection contour thereof, wherein the at least one casting channel is at least partially filled with the plastic material which forms the outer handle piece. A method is also described for producing such a hand-held tool.

A device for connecting a steering column to a cross member positioned between two A-pillars. The device comprises a front connecting region, a cross member-accommodating region, and a rear connecting region. The device comprises at least one metal structure, which is designed as a bow or comprises at least one such bow, extending from the front connecting region to the rear connecting region. A base body supports the metal structure. The metal structure is substantially the main load path for introducing force into the cross member. The base body is connected to the metal structure in at least the front connecting region and rear connecting region, in the direction of the main load path.
