How does Loctite work?

For Applications support, call 1-800-LOCTITE. You can talk to a person which is much easier than finding it yourself on a website.

Another tidd bit is never use around Plexiglas (acrylic) or Lexan (Polycarbonate). It will make it stress crack or craze overnight.

Very true as my friend found out after replacing his motorbike front mudguard 3 times due to cracking around the fastener hole.

The different grades work differently in some respects. Yes, the stuff is anerobic, however you might wonder why it does not harden in the bottles. According to some of what I have read, the bottle material is special in that it "breathes to prevent hardening. When trapped in the threads between a screw and a nut, the reduced access to air brings about the "hardening"

If you go to their web site you will find that is not true. There is nothing special about the bottles. The chemical reaction requires a catalyst which is in the metal.

So what's the common catalyst in copper, 316 stainless, Aluminium and Titanium?
My Locktite stud & bearing fit has worked with all of the above,

And why does the stuff that runs down the outside of the spout harden on the plastic threads?

locktite needs carbon and lack of oxygen to chemically transform. it will dry out and be a solid but not the same as when it reacts with carbon. high grades of alu and stainless will not activate it without the primer, which is iron oxide in a chemical carrier.
