I have a drawing which says to measure 3/4-16UNC-2A . I believe we do not have such call out in unified screw threads standard, it should be 3/4-16unf or 3,4-10unc.please suggest.
Thanks pmarc & drawoh,you both are very much right, but i have my drawing in that shape so i want to have Gage for that,without having any engineering change,can any body suggest ,how it will look like.
