Parallel vice with a basic body, guide rail, screw spindle and spindle nut. The spindle nut is designed as a device for reducing edge pressures caused by tension forces. For this purpose, it can be moved, under the effect of the tension force, together with the guide rail supported that on it towards the upper sliding surface until the guide rail is supported and clamped flat on this upper sliding surface.
