🔒 Loctite 29513 Blue 246 High Temperature Medium Strength Thread Locker - Maximum Temperature 450°F, 10 mL Bottle Review

Worked very well for my application using the rifle gas block set screws. The part has not moved since installation. I bought this item because it has a higher temperature than standard blue Loctite. The jar is small, true, but if used properly it will likely last for hundreds of uses.

Yes the bottle you buy is small but I think the price is reasonable for the size. Developed for high temperature applications, Loctite 246 is a superior choice over traditional medium strength blue threadlockers for engine applications. I had plain blue thread lock screws when they were used on my Harley engine.

Use this when securing nuts/bolts/bolts that will be exposed to heat. It is heat resistant to around 400-450 degrees Fahrenheit. I called Loctite tech support (I got it from a hardware store where I live) and asked what product would work for these situations and they told me to buy this product. I have used it on the bolts that attach the header to the head of a water cooled motorcycle. The parts are detachable, but the clasp needs to be heated with a hair dryer before removing.
