Link above from arf...see the last post.

Locktite-wise, green, blue, and red have increasing holding power, in that order.

What's your application???

hth

Purple is low strength. Green is the high strength stuff. Green is amazingly strong. Red usually works for most stuff. I had rocksett fail on a very well cleaned and properly applied and cured compensator on my open pistol, switched to loctite green and it never moves.

What number is your green?
The green I have is "sleeve retaining compound", not "threadlocking compound".

Rocksett is nowhere near as strong as red, but it's really good for high temperatures.

Red works for me. Stuff I used it on hasn't budged a Nm!

If you use Rocksett on Aluminum parts pretty much permanently stuck because by the time you can torque it off the aluminum will warp ( like some of my customers who used Rocksett to attached their forearms to the barrel nut).

The Loctite does have a higher strength than Rocksett but a MUCH lower temp to get it loose compared to Rocksett.

You aren't supposed to take rocksett off with torque, it gets chunky. You let it soak in water.

Randall, green 638 and 680 are called retaining compounds but I've used them forever as threadlockers and so have many many people before me. They are much stronger than red 271, and require more heat to fail. I can fail red loctite in a few minutes on my open glock compensator, rocksett came off after a day. Green has been through matches and thousands of rounds without a failure. 638 will take the slop out of threads or loose pins as a bonus.
Green 290 is the medium strength wicking threadlocker, although I've found 680 wicks as well.
I just test em, if they fail, they don't get used for that again. Not like I'm building airplane engines here, if my compensator spins loose I notice quickly. On cars, its not a big deal. You use what is close to correct

I think the green I keep around is 290.
I buy the higher temp red, preferring the thicker viscosity that stays where you put it so my red is 266 which has done better for me than 271.
You could also look at 2620 for your glock as that one is rated to 650f.

I still haven't had the current application fail, but if it does I'll keep using this 680. Very happy with it right now. I'm assuming I had a bad tube of rocksett, came from AAC. That stuff just didn't work at all when I started shooting it hot. At least loctite will melt and reseal. The rocksett fails into crud on the threads with no strength.

I haven't seen 2620, I'll try and find a tube.

I wonder haw Loctite 380 Black Max would work, I have used it to re attach the ventilated rib on shotguns before with great success...

I need to go back and find that thread about the guy who said anyone who uses loctite on a firearm is incompetent.

edit: here it is...lol

Loctite should never be used on a firearm. Its a sign of incompetence...People who use Loctite on firearms don't know what they're doing. It is not needed and when used on parts that get hot it is pointless since Loctite releases its hold when heated....You just needed to heat it up with a heat gun and it would have come right off. 482f I believe.

he was talking about the buffer tube on a semi AR15 getting this hot

The stupid is strong if he's using a thread locking compound on a buffer tube.
