I'm a nuclear test mechanic for the Navy. I use them when test fittings need to be locked into place so they can't be accidentally knocked loose. Our test equipment can be installed for a few days or for the entire availability of the boat. We can't always install it in places where it's out of the way so we do what we can to keep accidents from causing issues. For home use I'll probably not use them often.Are you an A&P mechanic?
I ask because most “mechanics” don’t even know what those are, let alone how to properly use them.
When I was in A&P school, we had an entire 3 week sub-course on how to properly safety-wire bolts and cannon plugs. You had to actually perform an entire 6 bolt safety-wire set to pass the practical part of the test. And, it had to be perfect.
It is actually a tool to measure bolts and nuts
That's how I do it.I just use a caliper and two little thread pitch gauges (metric and inch). Then you can measure any thread, could be a less common thread such as 1/2-28 or something.
They came in my Irwin tap and die set.

Head stamp should give it away
The nice thing about these or the ones I got is you can actually screw them into what you are working on. I’m working on an LS swap on my dad’s car and need a bolt to run into an existing hole on the block for a ground wire but I’m horrible at metric sizes.
