Direct screw connections are connecting elements that are screwed directly to the component without a mounting thread. The thread is produced automatically. The result is a firm and reliable connection with additional material consolidation. The screw thread of the direct screw connection creates the thread when it is screwed in without forming a chip.
Grooving threaded screws, self-drilling screws or self-tapping screws offer these possibilities. No work steps and effort are required. Direct screw connections are used for steel, non-ferrous metals, light metals as well as for plastics or wood.
