Is valid for the short taps specified in ISO 529 as well as for any other kind of ground thread taps with the same diameters and pitches. The internal threads produced with those taps are conventionally designated by the simplified denomination of "nut" in agreement with the word used in ISO 965 for the general designation of all internal threads.
