Thread gage marking 2A and 2B
Thread gage marking 2A and 2B
(OP)
Hi All
A simple question, would like to know your comments before I contact with the gage maker.
For the thread gage 1/4-28 UNF-2B, I know 2B means internal fit, 2A means external fit, I can not realize why 2A and 2B marked on the same gage, please ref to the attached for details.
Thanks for your inputs

Typically a double-ended gage like that would have a "GO" and a "NO-GO" end (with the NO-GO end often colored red.
So to me it looks like a typo - but on the gage itself. The packaging appears correct.
