Well, thanks for all of the thoughts on this subject.
From all of this I have deduced 2 things.
1. I don't need UN
JF position locators. If I am going to use a locator, the UNF version will be adequate.
2. I would probably be wasting time (and money) using a locator anyway. The value is dubious, depending on the particular thread and application.
What I will do is go with probing the holes with a spherical stylus and if/when the production folks complain that I should be using TP locators, I will let them buy one and we can then determine if they make any difference.
