EN The article summarizes the literature review in terms of currently used measuring methods for the evaluation of selected features of external threads. The work focuses on high quality requirements for threads produced for the needs of the aviation industry. The authors noticed that the classic measurement methods are mainly manual, but in recent years attempts have been made to automate the control of this type of elements. Selected methods found in the world literature, both manual and automatic as well as contact and contactless, have been described and compared in this paper. The authors attempted to examine selected measurement methods on three test pieces with different thread profiles: triangular, trapezoidal symmetrical and trapezoidal asymmetrical. A coordinate measuring machine, an automatic optical measurement device and a three-wire method were used in the research. The obtained results are presented and briefly summarized. It can be confirmed that it is possible to automate the measurement of selected features of external threads. The need for further research has been noticed.
