How It Works

This is the principle that makes everything possible. The rotating magnetic field of the actuator turns the screw inside the joiner. The fine thread is screwed into the threaded bolt in the opposite part to ensure a tight connection. The impact wrench effect of the INVIS joiner produces a knocking sound at the end of the screwing process (after approx. 5 seconds).  This indicates that the connection is closed and also ensures amazingly high tightening values.  To open the connection, the rotation of the actuator must be changed. It is held once again parallel to the joiner axes and the joint is opened without contact.
