The corollary is that threaded holes must only be “chased†which has a Unique tap (lesser pitch diameter). Even so I haven't been in the position to confirm nor get a metric “chase tapâ€. Unlike American standard inch dimensions wherever the thread root could vary in dimension, the metric common has only one thread root configuration.
