  • Method and apparatus for setting a screw
    Patent number: 10981213
    Abstract: The invention relates to a method and to an apparatus for setting a screw, in particular a flow drilling screw. In accordance with the method, the screw is driven at a first revolution speed and at a first axial feed force during a time-limited first phase to drive the screw through at least one component. In the event that the screw does not penetrate the component during the first phase, the screw is automatically driven at a second revolution speed that is higher than a first rotation speed and/or at a second axial feed force that is greater than a first axial feed force during a second phase subsequent to the first phase.
