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

Yes, the bottle youre buying is the small size but I think price is reasonable for that size. Loctite 246 is for high temp applications, making it a better choice vs regular medium strength blue threadlocker for applications on engines. Ive had bolts with the regular blue threadlocker come loose when used on my Harley engine.

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.

Heat is the enemy of Locktite joints so using the high temperature variety helps keep things secure. However, intentionally heating the joint for easy disassembly becomes less effective, so use only when joints are exposed to a high temperature environment.

For the person that used this product on a model plane muffler. According to the instructions, the product is best used on 1/4 to 3/4 inch threads. I’m curious if your application was outside, or within that specification? If outside this would be an explanation of failure.

Shows large bottle, get a small bottle for the price of the large. Rip off.

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.

Expensive but works great.

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!

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

Perfect for engines.
