Tired of measuring Buttress Thread groove widths using old Go/No Go gages or by hauling mold samples to an optical comparator?

As an easier alternative, Gagemaker now provides a gage to directly measure tooth width easily wherever the part is. The TW-6001 gage comes equipped with a .0005″ reading indicator to inspect those groove widths and provide a quantifiable measurement.


A setting standard allows you to set the gage for both pin and box threads. There is a separate standard for ¾” and 1″ Buttress. Setting standards sold separately.

Be on the lookout for this inspection in the new API 5B Spec!
