Specifies the verification, by means of limit gauges, of cylindrical threads, the dimensions and tolerances of which are given in ISO 228-1. For industrial applications it may be necessary to provide for several GO and several NOT GO gauges: a) the threaded GO gauges shall ensure that the profile of the machined piece does not exceed the maximum of material provided for by the tolerances applied to the dimensions of the profile defined by ISO 228-1;b) the threaded NOT GO gauges for the threads of the pieces fix the minimum material limit on the flanks of the thread.
