Heli-Coil螺纹塞规编号(公制)


Heli-Coil STI Thread Plug Gages (metric) for checking the tapped hole are listed below。
 
The complete gage consists of the GO thread plug gage,the HI thread plug gage and the appropriately marked gage handle。
 
Accuracy of the finished thread,when the insert is installed, is dependent upon the accuracy of the tapped hole。If the finished tapped hole gages satisfactorily,the installed insert will be within the thread tolerance。It is,therefore,not necessary to gage installed insert。
 
After the insert is installed, the GO thread plug gage may not enter freely;however,the insert will always seat itself when the bolt or screw is installed and tightened。(Reference MA1567)
 
When gaging tapped holes which have been thoroughly cleaned or which have a protective finish applied,the gage should always be lubricated with light oil。
 
The HI thread plug gage may enter provided that a definite drag results on or before the second turn of entry。 (Reference ANSI B1.16)
