Method and Device for Directly Screwing Together at Least Two Components Without a Pilot Hole Using a Holding Down Clamp

摘要

A method and device are provided for directly screwing together at least two components using a self-drilling and tapping screw which has a head and a shank formed onto the head with a self-tapping thread section and a hole-drilling section for flow drilling. The components are held pressed against one another by a holding down clamp while the screw is screwed in. The holding down force, with which the holding down clamp presses the components against one another while the screw is screwed in, is varied.

1. A method for directly screwing together at least first and second components using a hole-drilling and thread-cutting screw, the screw having a head and a shank integrally formed on the head, which shank includes a self-tapping threaded section and a hole-drilling section for flow drilling, the method comprising the acts of:
pressing the first and second components against one another via a holding down clamp during the directly screwing together of the at least first and second components; and varying a holding down force with which the holding down clamp presses the first and second components against one another during the directly screwing together of the at least first and second components.
