Interesting. I had never seen these so I did some googling. These are patented as anti-theft, and are a replacement for needing to weld towers together since they can be installed using basic tools and will not loosen. I suspect that if there is a need to remove them, they have to either split the nut or cut the stud out.

I am curious why install the counter nut also? Just to be extra safe?

Lol.

At the same time, wondering if the proliferation of these gifs are often surreptitious; conveying information used for counterfeiting/ infringements of patents and processes?

The nuts appear to have a scoop cut in them that goes up to a square-ish shoulder. I wonder how they machine that squared off part.

Interesting. Those are Pal nuts, I thought they had died out. Chev used then on the rod bolts of stove bolt straight sixes, last century...
Apparently, they are still alive and available.
