WebbThe ISO Standardisation Authority defines strict specifications metric threads. This is to ensure compatibility with mating components. The table below shows various dimensions and the required tap drill diameter of coarse and fine threads M1 through to M68. Tolerances should be considered when designing products. WebbIn this respect, it is necessary and prescribed to extend the designation by the thread pitch. Example: The designation for a standard thread is M 10. The pitch 1,5 is clearly defined in the DIN 13-1 standard. For a fine thread M 10, the following pitches are possible according to DIN 13-2: M10 x 0,5; M10 x 0,75; M10 x 1; M10 x 1,25

These threads are also used for line adjustments and where the connected parts are subjected to increased … WebbThe 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. To simplify metric thread callouts, the international (ISO) standard for metric threads eliminates the pitch callout on coarse threads. For example, the thread "M10 ... tapered fade with parts for women
