I have all kinds of information on how to properly specify an internal thread on a drawing but not so much about external threads.
On an internal thread I can specify the standard tap drill size required to produce the specific thread.
When I specify UNC and UNF external threads on the end of a shaft is there a corresponding set of standard diameters that I could call up to produce commonly used UNC and UNF external threads
Right now I specify only the size the type of external thread required and no other information. Perhaps this is the proper way to do it but I would like the input of those who have to make the threads so I can do a better job of specifying them.
