The loctite is a great price. The thread lock is excellent for automotive fasteners.

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.

This was recommended Works great!!
I bought a cast iron knight fireplace set on Amazon. I read a review and the person said that the nuts and the bolts to hold the utensils together would come loose so he recommended using Permatex Threadlocker Red. I bought this on Amazon and it did the trick. The heat of the fireplace does not affect the glue at all.

Red Loctite 272 High temp alternative
Very pleased with the Permatex High Temp Red 24026. I employ this to secure the set screws on AR15 low profile gas blocks, which are exposed to very high temperatures and, if they fail, would cause the entire gun to cease functioning. Most of my work is on law enforcement patrol carbines and rifles, so ensuring proper function for the people that protect all of us is VITAL. This is rated to maintain 90% of its holding strength up until 450 degrees F. However, and this is good news, it states that you must heat it to past 600 degrees F to begin to remove it...and even then it requires substantial amounts of force (think "breaker bar" or a miniature equivalent) to break the fastener loose. This protects against vibration loosening and ALSO protects the threads from corrosion via oxidation. I recommend this for any item that is being installed in a "permanent installation".....i.e something that simply cannot come loose unless a MAJOR repair or planned parts replacement is begun. AR15 gas blocks, engine bolts, etc. You can remove it via the judicious use of a blow torch and a lot of elbow grease, so this may make it unsuitable for some smaller fasteners or weaker setups (or aluminum if you want it to NOT be permanent). For fasteners that you may want to remove, use a blue variant (either Loctite, Vibra-tite [my favorite], or permatex blue).

Much better value than actual LOCTITE brand name. Does the same thing at a fraction of the cost of a bottle of LOCTITE brand.
