Metric Coarse Thread Gauges

Cutwel stock a wide range of go and no go thread gauges from JBO (Johs Boss) and Insize. We offer go and no-go gauges thread ring gauges and thread plug gauges in all major thread types including metric coarse, metric fine, UNC, UNC, NPT, NPTF, PG, BSF, BSW (whitworth), Trapezoidal and BSP (British Standard Pipe). 

For best quality practise, go and no-go thread gauges should be used together.  Go thread gauges are used for gauging the effective diameter of the thread. If the go thread gauge fits the thread, the work peice should be accepted. The no-go thread gauge is an oversized gauge also used for gauging the effective diameter of the thread.  If the no-go thread gauge fits the thread, the work piece should be rejected.

Our range of thread gauges are also available in TiCN coating and different tolerance levels (please contact us for prices).   UKAS calibration is available with a 5 day lead time.

Metric thread gauges are available in left or right hand, in 6H or 6G tolerance.
