Thus, the contact surfaces are increased, enabling a surer grip of the ring and a higher transmission of forces. The service life of the screws is increased, because wear to the corners of the screws is avoided. Even old and rusty screws can be loosened without problem with the POWERDRIV ® . POWERDRIV ® The POWERDRIV ® - system was developed for particularly high demands in aviation, in order to enable highest accuracy of fit. It permits a higher transmission of forces in the ring and gentler distribution of loads on the screws.
