METHOD AND DEVICE FOR DIRECTLY SCREWING TOGETHER AT LEAST TWO COMPONENTS WITHOUT A PILOT HOLE USING A HOLDING DOWN CLAMP

摘要

The invention relates to a method for directly screwing together at least two components (310, 320) using a self-drilling and tapping screw (200) which has a head (210) and a shank (220) formed onto the head (210) with a self-tapping thread section (221) and a punching section (222) for flow punch forming, wherein the components (310, 320) are held pressed against one another by a holding down clamp (120) while the screw is screwed in. According to the invention, the holding down force (P), with which the holding down clamp (120) presses the components (310, 320) against one another while the screw is screwed in, is varied. The invention further relates to a device (100) for performing the method.
