Version

Note
These power clamping screws are fitted with a patented wedge mechanism. This system allows the greatest clamping forces to be achieved at low torques with a simple manual operation. The wedge mechanism is self-limiting in every clamping position. A longer path can be quickly traversed via the external thread of the screw before the wedge mechanism (travel up to 2.2 mm) is used for clamping. Tightening screws are used for many purposes, primarily in presses, punches, production machines, fixtures and equipment production.
