HeliCoil Thread Plug Gauges & Extraction Tools
Thread Plug Gauge
The accuracy of the finished thread, when the insert is installed, is dependant on the accuracy
If the tapped hole gauges correctly, it is not necessary to gauge the installed thread insert as the installed insert will be within the thread tolerance.
After the HeliCoil insert has been installed, the Go Gauge may on occasion, not enter freely. However, the insert will always seat itself when the bolt or screw is installed and tightened.
Where there is a need to remove a threaded insert , the HeliCoil Extraction Tool is
used. The extracting tool has a hardened gauge steel blade which is ground to dig into the top
coil of the installed insert. With this tool, quick removal of inserts without damage to the
workpiece surface can be achieved.
