Helical Coil Thread Plug Gages (STI)

During thread building / re-building operation the tapped hole plays a major role and the accuracy of finished thread after the insert is installed completely depends on the accuracy of the tapped hole. Therefore determining its accuracy is very important. If the finished tapped hole is accurate, the installed insert will be within the required thread tolerance.
 
Rapi-Coil STI Thread Plug Gages (Metric) give the correct and accurate parameter to gage a tapped hole prior to installing the Screw Thread Wire Insert.
 
Our Gage handles and nibs are marked with the extreme product limits for the particular size and class of fit. For best results
 
the Gage should always be appropriately lubricated before gaging thoroughly cleaned tapped holes.
