Is there a reliable thread locking compound for over 800 degrees F continuous ?

(OP)
The best Loctite says 650 F limit.
There is no room for metal locknuts etc.
These guys' claims are interesting.

You can find cements that will work, but you will never get them loose. So any repair will involve cutting them off and replacing them.

The other choice that comes to mind is water glass, but it's messy.
I'd try real hard to find space for French locks or Stage 8 locks.

food for thought:
there is an interference thread fit category. its not used much, but its there. you need to HEAT the nut to expand it to the proper thread diameter so that it screws on to your threads. when it 'cools' to the operating temp, it shrinks and wrings on to the threads. when i was a wee tot, we made some custom machine bolts that held together a forging press. we had to heat the nuts to assemble the thing, and had to that right quick too, turn-of-the nut method to make sure we got pretension because no way to do proper torque.
don't forget that mother nature has given us many clever tools to use. sadly we neglect most of them when there funner toys to play with like glues and welds...

They simply won't turn in the reverse direction under load.
