  • Method for producing an adhesive screw connection using a flow drill screw, and flow drill screw usable therefor
    Patent number: 10393165
    Abstract: A method for producing an adhesive screw connection between at least one upper component and at least one lower component using a flow drill screw, and a corresponding flow drill screw are provided. In the method an adhesive is applied to at least one of the upper and lower components, the flow drill screw penetrates the upper component at the joining point through a pre-drilled hole, and the flow drill screw is screwed into the lower component to form a flow-drilled hole and to join the upper and lower components. A protective ring through which a screw shank of the flow drill screw passes during the screwing-in operation is located in the pre-drilled hole. The protective ring may be capitvely held on the screw shank of the flow drill screw.
