The software product QMSys Threads and Gauges is a program designed for engineers, quality control managers, mechanics, etc., and its purpose is to save time and prevent human errors in determining nominal and limit values of thread parameters. The calculated results are based on international standards and comprise information about values and tolerances of threaded products, working gauges, plug and ring gauges as well as check gauges.
QMSys Threads and Gauges comprises data base and methods of calculating the nominal and limit sizes of the following types of threads:

For determining the pitch diameter during measurement by the 3 wire/ball method, the limiting values of the outcome from measuring by the method described in the publication EA – 10/10 are additionally calculated.
