Permatex 27200 Hiigh Temperature Threadlocker Red, 10 ml

It holds fasteners securely even under high heat. The 10 ml size is perfect for various projects, and it’s easy to apply. It has proven to be very effective in preventing loosening.

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.

Nice to work with but this tube is way too small for professional use. It’s great for a car or two so it should be sufficient for home mechanics.

Used to hold the Heli Coil on a triton motor. So far working great

Very good product,fast shipping

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.

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).

It securely locks threads and withstands high temperatures. The 10 ml bottle is easy to use and very effective. Great for keeping bolts and screws in place.
