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

Absolutely love this stuff! There bolts on my car exhaust mid pipe would always vibrate loose. A couple drops of this and It stopped all bolts from backing out! Great stuff!

Always love blue loctite, but whether or not intentionally, the image misrepresents the sale item. You will not receive the large bottle, but rather the tiny bottle. Nobody loves the tiny bottle, unless you also carry loctite in your purse, which I do now.

Not much to say really. I wanted a thread locker that was going to remain strong at up to 300F. this 246 stuff claims to go up to 450F and I have no reason to disbelieve that. My jam-nut is still tight after 2 months on/off heat and vibration going from room temp to 2-300F.

Great to use in transmission and differential plugs.

Works as advertised. Dont skimp. Get the Loctite brand!

Hard to find this type. Ok price.

Just what I wanted.

the picture clearly shows a 50ml bottle only if you read the discription closely it says 10ml which is too expensive for this. worst is i cannot return it. Very misleading.

A $5.00 bottle for $18.00. The item in picture is not what you get. Very Deceiving!!!!!!!!!! CAN NOT RETURN Check customers reviews!!!!!

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.
