If I have sufficient material to do it I like to turn a portion of the work to the minor diameter of the thread. When the threading tool just marks the minor diameter, the thread is to size. I cut off that portion after threading. I use a similar approach on internal threads.
 
For a down and dirty depth of cut for 60 degree U.S. threads....
0.866 divided by number of threads you want.
Should get you there...
