Checking My Nuts

[Vinny]

I've thought about a similar approach but instead of two springs I was going to use one larger one around the screw. A second approach was to drill 2 or 3 holes around the outside, tapping and dropping a ball bearing in and spring loading it. Two things I haven't been able to hash out was 1) how do I get the holes to end up in the right spot to catch the lowest part of the thread and 2) would this approach really even work.
