An-cor-lox nut has a ring of soft metal, such as soft steel or brass at the bottom of
the nut which turns on freely until the nut strikes the part.

No longer made.  Company gone.  Basically a soft copper washer that is
squished into contact with the bolt thread.

I've also run into Spiralock, which looks quite interesting.

Spiralock has gone out of fashion as they are a "single use" locknut
if I remember correctly from my Fiat Allis days - both nut and bolt to
be replaced at every use. Not an issue for NASA as NO bolt gets
re-used - - - but a pain when repairing a loader/backhoe in mud up to
your ankles- head first!!!

Good point, although the nuts are pretty cheap, so one can afford to
just replace them.  The U-straps may also need to be replaced?

Their Key-Lock thread inserts work pretty good - never had one come
out with the bolt/stud unlike HeliCoil.

And you don't need to replace the thread insert after one use?
