If you won;t something threaded to stay locked down this is it
It will take heat to remove your nut or bolt if you apply this to the threads. I repaired two hose reels and used this to lock the swivel fittings where they screw into the o-rings and the frame . When you wind the hose or unwind, the fittigs don't come apart. Also works well on anything bolted down making it theft resistant . I have used 271 for years to stop unwanted looseing of nuts and bolts.

Great size if you use a lot of it.
I race nitro off road 1:8 scale and this stuff is great after you building you car and putting it back together with locktide. Never hurts to be safe with this high vibrating nitro buggies.
