Wedge clamp with serrated clamping jaws

Clamping with the wedge clamps GN 920.1 is achieved via the socket cap screw and the clamp wedge which cause both clamping jaws to move outward. When loosening the screw, the clamp wedge is returned via an internal return spring which, in turn, loosens the tension. Wedge clamps are ideal for multiple clamping operations, but they are also suitable for clamping individual workpieces. The slotted hole in the clamp wedge serves to compensate tolerances in the workpiece.
