Method for producing a screw connection

A method for producing a screw connection having a screw that is set in rotational motion with a screwdriving head of a screwdriving tool. The screwdriving head has a motor drive for creating the rotational motion of a screw receptacle of the screwdriving head. The screw is driven into at least one mating part of the screw connection in a rapid speed. A torque is detected with which the screw is driven. The rapid speed with a higher rotational speed is changed to a creep speed with a lower rotational speed at a changeover time. The changeover time is determined as a function of the detected torque during screwdriving at rapid speed. The screw is further driven at the creep speed until a head contact time when a head of the screw makes contact on the mating part.
