Thanks Ed.
Can you tell me which reference you're using? I'm going off of this one,
http://www.carbidedepot.com/formulas-tap-standard.htm .
I'm only seeing .3125" as major diameter for 5/16" which makes sense since .3125"=5/16"
What am I reading/comprehending wrong in this chart?

If it's crazy but it works, it's not crazy.
