I am looking for a fine pitch thead for a 2.00" nut, it would be a 16-UN series thread but can't fine it in hole wizard. What doe's a person do? Is there a download with more thread sizes?
You could look it up/do the calculations using the Machinery's Handbook or purchase a thread calculator like ME ThreadPal.
For thread sizes try http://www.efunda.com/designstandards/screws/unified.cfm?start=473&finish=574
For info on how to add more sizes to the database;
