A method for determining a geometric parameter of an axial cross section of internal or external screw thread, comprising, with at least one probe, mechanically probing in radial direction two screw thread profiles of the screw thread to be measured, at two probing positions which are located diametrically opposite each other and which are both situated in a plane through a centerline of the screw thread, measuring a distance in said plane through the centerline of the screw thread in radial direction with respect to the screw thread between the probes in probing position, while the at least one probe is a wedge probe, the method further comprising the setting of a probing width of the at least one wedge probe, determining the geometric parameter on the basis of the measured distance between the probes in probing positions and a pitch of the screw thread.
