The 1" looks ok but the others are a bit odd.

The numbers don’t quite match the tables?

The only bit that's relevant on these gauges is the pitch number.

A 12 pitch thread for instance can be on any diameter and they still work fine measuring British [ 55 degree ] or American [ 60 degree ] threads.

Not even sure if mine have any other info on them as I never look.

Every set is different. I think they feel just putting the one number for pitch won't look clever enough so slap on a bit more.

I wonder what our 'Brand' team would dream up, apart from having to be red and have a blue LED on it. What! they want to charge per letter! Not paying for that, why do they need these numbers on them anyway, just make them all the same size and only put the company logo on.
