Loctite 29513 Blue 246 High Temperature Medium Strength Thread Locker, 450 degrees F Maximum Temperature, 10 mL Bottle

The picture shown is for the 50ml container, not the 10ml

Use this if you are fastening nuts/bolts/studs that will be subjected to heat. It is heat resistant to around 400-450 degrees, F. I called Loctites tech support number ( I got it from a fastener store where I live) and asked which product is good for these situations, and they told me to buy this product. I was using it on studs that hold headers to the head on a water cooled motorcycle. The parts are removable, but you will need to heat the fastener with a heat gun before removal.

It works well, but the bottle is WAY to small to warrant the price.

I used this on a remote control airplane engine muffler that I temperature check and the temp was within spec for this product but the muffler constantly came loose.

Great to use in transmission and differential plugs.

great

I love this high temp version! but it might be harder to remove if heat is required....

Perfect for engines.

Worked very well for my application, seating the set screws for a rifle gas block. Part has not moved a bit since installation. Bought this item because it has a higher temperature rating than standard blue Loctite. Bottle is small thats true, but likely is enough for hundreds of applications if used properly.

Great product
