The program allows you to determine the thread pitch, the average, inner diameter of the bolt and nut, as well as the inner diameter of the bolt along the bottom of the cavity by the outer diameter of the bolt and nut. Diameters from 0.25 mm to 600 mm are available. Also, by the step of the thread, you can determine the sizes of runaways, undercutting, grooves and chamfers. Steps from 0.2 mm to 6 mm are available. There are illustrations for all thread elements.The steps and diameters of the threads are taken from GOST 24705-81. The sizes of runaways, undercutting, grooves and chamfers are taken from GOST 10549-80.
