VÖLKEL STI Precision Thread Plug Gauges – all dimensions available from stock!
When repairing threads with V-COIL thread inserts, it is often necessary to check the accuracy of the thread before installing the insert.
Since the holding threads cut with V-COIL STI Taps are specially dimensioned for the thread inserts, it is not possible to use Precision Thread Plug Gauges for standard threads.
Appropriate STI Precision Thread Plug Gauges must be used.
1) Checking the holding thread, cut with an STI Tap, by using a STI Precision Thread Plug Gauge – before installing the V-COIL thread insert.
2) Afterwards checking the dimensional accuracy of the V-COIL thread insert, installed in the holding thread, with a Precision Thread Plug Gauge for standard threads.
