WebMetric thread callouts are fundamentally different because the thread pitch is specified instead of threads per inch or per mm. The thread pitch is the distance between each thread in mm. For example, an M10x1.5 (coarse) thread has a 1.5mm pitch, while an M10x1.25 (fine) thread has a 1.25mm pitch. shsb school
