Permatex 27100 HIgh Strength Treadlocker is jus that - strong!!!
This product states that it will require heating up the parts secured with this threadlocker to 500 degrees in order to separate the parts after the threadlocker cures, so you really need to be sure this is what you want it to do. It was exactly what I was hoping for, and it worked flawlessly by holding a barrel nut in the handle of my Colt 45 that had a screw that would not separate from the barrel nut. I put the threadlocker on the barrel nut, attached it to my Colt, and the next day - today, I was able to get the screw out of the barrel nut, but it took some force to get it to break free. The barrel nut did not budge at all, so kudos to Permatex!

Locking tighly.
Great product and this little tube does the job and keeps on going. I was in search of a high temperature thread locker for a high performance engine rebuild. Product arrived fast and was reasonably priced, actually it was a few dollars cheaper than the retail auto stores. Permatex worked great in the application I needed it for and now I have plenty of left over thread locker if needed in the future.

It applied easily and seem to work well
I needed a threadlock for a couple of small set screws going into aluminum on a mower cylinder head. This went one easily and dried well. I did not try to remove the small set screw after it dried because it is something that will never need to be removed,, so I cannot say how tightly it locked the set screw in place. A little bit goes a long way, so the small tube will last me pretty much forever.

Make sure you shake it first
normally I use the blue thread locker for everything. I used the blue to hold a compensator on gun which had to be a specific orientation. After a couple hundred rounds it started to twist. This is when I looked in to how thread lockers work and more importantly that you loosen bolts and such by applying heat. Guess what happens to a compensator when you fire it? Yup. Bought this and for whatever reason thought it's in a tube I don't need to shake it like the blue stuff. Took to range next day and started to turn almost immediately. Realizing the err or my ways I shook it and applied again. It hasn't budged since One downside to this setup is to completely remove barrel requires to unscrew compensator. So at some point I'm going to have to be able to do that. I'm using a bore snake to clean barrel without removing it but at some point I'll try and heat it up with a heatgun and see if it nudges. I'll update this if I remember.

So far so good
Just put some spacers on the Jeep and used this for some piece of mind. It’s been about a week and I re-torqued the nuts on the spacers they didn’t budge and all of them were perfect where I torqued them when I first put them on. If anything bad happens I’ll update this but it seems to be quite perfect to me. Please click helpful if you found this review of any help it would mean a lot.

Excelente pegamento.
Lo utilicé para fijar el tornillo de una sartén, y vaya que cumplió lo prometido, a pesar de las altas temperaturas de la estufa de gas L.P. el tornillo se mantuvo fijo un par de meses, hasta que por el uso diario, y el detergente para trastes, se comenzaba a aflojar. Terminó por romperse la pieza donde iba el tornillo, antes que este se despegara. Definitivamente lo recomiendo.
