I don't see why Loctite would not work as long as the threads are cleaned and degreased before using it.

Double nutting can also work if there is sufficient threads.

I have only done this a few times. If once the Nuts are tightend down there is at least 4 good threads showing you can coat the exosed threads with JB Weld Epoxy. The nuts are not going to back out by themselves like that.

When I needed to remove the Nuts I used a Propane Torch and it quickly burned the Eopxy off and allowed my to back the Nuts off.
But, after that you need to chase the threads with a Die and or wire brush to get the old Epoxy out of the threads.

Whan I had a Truck and or Cars for about 10 years of My life my main transportation was a Motorcycle. Things come loose on them. I already had the JB Weld and no Loctite.
