I have exactly this issue on a very small part that requires 7/32x40ME… It only projects about 3/32nd – 1/8"
Did anyone manage to grind or mill out the lead out from a carbon steel die?
I notice also the post from Greensands… my brass hex external is 7/16. I'm guessing I could make just a 7/32×40 threaded bar, and silver solder a 7/16" brass nut to it. Got me thinking, but…. bit annoying that I can't just buy one as needed.
Cheers chaps
