Nyla nuts

Valid point, but just noting that using both for "extra assurance" doesn't always work.

On the plus side, gasoline doesn't affect it, I found a hole in a 5 gallon gas can and plugged it with a stainless button head screw and a nyloc nut on the inside... that wasn't fun to get into place

MY fail safe has always drill a hole on end of pin or bolt and a cotter pin....

Jam nut it and be done. I always use a jam nut in a situation like that.

If there are enough threads... in my case there aren't.

Actual "jam nuts" are about half the thickness of regular nuts. Use two of them.

Looking at you photos, it appears to be enough threads for jam nuts. Could you get longer bolts then jam nut them?

Yeah that might work!

Just took a closer look at a few of them and sure enough, one nut was a couple of turns from falling off! Others were in various stages of 'unscrewing' most likely from vibration. None are tightened up... not even sure they can be tightened without bottoming out the nut on the shank of the bolt. I suppose that was their thinking in using nyloc nuts as they wanted the pins to be loose.

There is room to install a thin jam nut but I wonder how effective that would be if there is meant to be a gap?

The jam nuts can be at the end of the bolt and still hold. As long as there is enough threads in the nut so it doesn't strip. But getting a little longer bolt is probably an option as well.

I'm thinking cheap and quick and since most of them need tightening as it stands.

Back the nuts off a bit... shoot the gunk off with some break cleaner, blast with a little air, and add a drop of blue loctite and tighten up some. There are actually a lot more of these joints than I previously realized.
