Helicoil Ring Gauges:
Go Gauge and No Go Gauge are all called Ring Gauge which is used for inspect the external threading.
Ring gauges are used for checking, calibrating, or setting of gauges or other standards.
Helicoil Plug Gauges:
Helicoil Gauge is generally used wherever precision threads are required. The quality of the tapped hole accommodating 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 measure the tapped hole to ensure optimum insert performance once installed.
