The principle of non-cutting forming used here produces a thread with high load-bearing capacity due to the uninterrupted grain flow and strain-hardening of the material. Additional screw locking (e.g. to DIN 267-27/28) is therefore unnecessary.
The generated thread is a metric ISO thread, which is compatible with standard parts. Furthermore, the threads formed in this way are free of play and are self-locking. Thread-forming screws can be used in all ductile, i.e. plastically deformable materials.
