For your buttress connections to be compliant under the 16th edition of the API 5B, you must inspect either the groove width or the tooth thickness.

Gagemaker groove width Go/NoGo gages (GW-1000 Series) are a quick and easy method to check your groove width. If your inspection shows a problem or a failed part, you should inspect with our TW-6001 Tooth Thickness Gage.

The TW-6001 will help you determine your problem by providing a more detailed, quantitative tooth thickness (shave).
