That is what I have been thinking. That these could be heavy duty Tap ratchets. And a tap would be heavy enough for I D threads.What does a large NPT or BSP tap use to drive it? Honestly not sure, but if it was a 15/16" square, I could see why they were called "pipe threaders ". Kind of like how Greenlee has a "wrench" for their slug-buster cutting plugs. (it is just a ratcheting box end).
