Abstract

The invention relates to an apparatus (10) for testing threads comprising a thread plug gauge (11) which can be screwed into a thread (2) tapped by a machine tool, and a connecting member (14) with which the apparatus (10) can be exchangeably arranged at a tool spindle (20) of the tool machine, and wherein a sliding clutch (12) is arranged between the thread plug gauge (11) and the connecting member (14). The invention relates furthermore to a method in which signals (100) from one or more signals transmitters which are related to screwing-in the thread plug gauge are acquired, in which a reference curve (210) of signals related to screwing the thread plug gauge into a reference thread is stored, and in which the reference curve (210) and/or a curve or magnitude derived therefrom is compared with the signals (100) and/or a curve or magnitude derived therefrom.
