Thread gauging is recommended wherever precision threads are required. The quality of the tapped hole which accommodates the insert determines the finished size and hole quality after the insert has been installed. If the finished
tapped hole gauges satisfactorily, the installed insert will be within the thread tolerance.
Gauges are supplied for two different classes of fit (tolerances).These are close and medium tolerance. Gauges are used to check the pitch diameter of the tapped hole; the “NoGo” end of the gauge checks the pitch diameter is not too large and the “Go” end checks the pitch diameter is not too small.
