These units are used for shearing and shaping the sheet in order to achieve the “twist” or “spiral” in the sheet itself, so as to tighten the self-tapping screws, avoiding the use of a standard collar made at the tip end, which is not reliable. The special shape obtained by these units improves thread tightness. It is also possible to manufacture special models, adapted to your needs.
