manually measured thread.. stupid question.
(OP)
I've been asked to have some parts re-made.. But the old drawings have been lost in the abyss. So, I had to get out my thread gauge and micrometer/caliper.
The question is: If i measure a male thread at 1-5/8"-12, and the female at 1-1/2"-12. What am I going to call out for the respective threads in the drawing?
Do I call out 1-1/2"-12 or the 1-5/8"-12? I'm not sure which correlates to the tap/die sizes.
Sorry this is kind of a stupid question... but hey..

1-5/8-12 UN 2B for the female
The ID of the female thread is ~1-1/2"

Just measure the easier to access male.

Also, like I said in my original post, I didn't know whether I needed to call out the male or female diameter.
But thank you all.
