Sure, one would expect that most chainring bolts don't loosen under use. That doesn't mean that they are immune from it.

If I told my boss that this fastener will work fine 99% of the time, he'd yell at me.

Ha! I had no idea such a tool exists! Nifty.
Or just do like I said, keep the outside of the nut dry but lubricate the threads inside, and that nut will never slip while tightening.

Never had an issue with it. Are you sure you know how to use it?

I know how to use it and wish I had one in my toolbox. Recently, I've been using the tool pictured below to hold the nut. On the left, is it's closed position and it's open on the right, which is how I've been holding those tiny slits on the nut. It's tricky but works. I've even managed to hold the nut with the tool in it's closed position, albeit with it spread open more inwardly.

I don't even remember where I got that thing or even what it's used for. But one day, after trying and failing with tiny screwdrivers and coins, I looked at this little tool and said, 'Hey, this might work.' You can't see it but the name Belkin is embedded into the black rubber outer. I haven't bothered to look it up. Y'all can if you like.

To the OP: I'll join in with the others here who have stated that a little grease on the bolt threads is all you need. Never had one loosen when I practiced the proper tightening sequence.
