Whitworth Thread Gauges (BSW/BSF)

Whitworth thread gauges are available right hand for measuring BSW (British Standard Whitworth) and BSF threads (British Standard Fine).

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.
