It's like super glue on hot bolts
A must have addition to anyone toolbox. Iconic for it's durability and holding power, this model specifically designed to withstand heat typically as a result of some motor running

Works well
I bought the Loc-tite to hold a stud in a Model A accessory heater exhaust manifold. It gets pretty warm and I wanted to be sure the stud didn't pull out. I've driven the car several times since using the Loc-tite, and the stud is holding fine. I'd know immediately if it didn't as the heater cover would rattle like crazy. If you need a product to hold in high temp situations, it works well. The shipping process was terrible, but that has no bearing on the effectiveness of the product.

High-temp Red!
Can't buy this anywhere locally. This is great for high-temp uses in gunsmithing (muzzle devices, gas block) and other high-temp needs. I can break it loose with a heat gun and standard wrench if needed.

Locktite 272 high temperature locking compound.
Impossible to find locally. Fortunately Amazon had it & it worked great. Very happy buyer.

Rock Solid
Not really sure about this. Used on a Glock 43 to lock a compensator on an aftermarket threaded barrel. Have not used at the range yet, so don't have first hand experience about the power of the product. I can say that I can't budge it with my bare hands and doubt a session at the range will give it much more of a fight. A large number of people are using this to hold compensators on threaded barrels, and have no complaints. My two cents, get some. Lost a star for the price.

The Classic High Strength Threadlocker
I’ve been using this product for 30 years and it’s always been good. Bolts and nuts won’t back out and will need some serious impacting and/or heat to remove. This nice sized bottle will last me a good long while. Also, I highly recommend the Loctite 242/243 threadlockers as well.
