HeliCoil Gauges & Extractors
HeliCoil Thread Plug Gauges
The accuracy of the finished thread when the HeliCoil insert is installed is dependent upon the accuracy of the tapped hole. If the finished tapped hole gauges satisfactorily, the
installed insert will be within the thread tolerance. It is not necessary to gauge the installed insert.
After the HeliCoil insert has been installed, the GO thread plug gauge may not enter freely. However, the insert will always seat itself when the bolt or screw has been installed and tightened.
HeliCoil Extraction Tool
Where HeliCoil inserts need to be removed from the hole after installation, they may be removed manually with little effort using the HeliCoil Extracting Tool. Removal is done by applying the extraction tool to the insert, giving the head of the tool a light blow with a hammer, and turning it counterclockwise, maintaining steady downward pressure.
HeliCoil Extraction Tools can be used to remove free running and screw lock inserts.
