Does what you need on smaller threads.
The first thing to understand is that this is non-permanent and designed to prevent breaking smaller threaded parts when removing without heat or impact. It can be messy if you use too much, but that’s on you! The bottle is a good design. Store it upright to prevent leaks. Shake well!

Great thread locker!
Great product and works as expected. Reasonably priced. I will definitely be buying more in the future when needed. Highly recommended.

Useful for securing screws and yet soft enough to rework later.
My application is for my RC hobby, both builds and maintenance. I’ve only used it on a few parts so far, but so far it is working exactly as I hoped, a quick and secure connection that can also be reworked without stripping anything out. There’s plenty in the bottle, half is air which keeps it liquid. Once you get it into a threaded connection is begins to harden. Tip is a bit large for hitting tight spots but I use a sharp thin metal tip to guide small drops into tight locations. If you leave some on a surface it’s easy to wipe off.

Just saying!
Did a great job on a metal frame for a Queen size bed.... Have had it ( the frame), for a while. Not going to bad mouth any other brands. Bought this to see if it could help even with the wear and tear of the past. Had previously used a popular brand but for what ever reason it failed immediately, (in a week or so.. Had waited to give it time to set and cure) . The Eskonse thread blocker Blue 234 actually has held and I even gave it the week to cure just like the one I havd been using previously. This thread locker worked after the same curing time, on the same frame and is still working 2 weeks later.

This Item has become on of my favorit tools. I keep on hand.
I bought the lock Tite for locking and red one and two blues. I was a little confused I read it but it didn't set right in my mind. well they came in a little box, I mean a little great stuff on time and value is worth it. If anyone needs to lock up a nut or bolt this is for you. If you don't like it , give it a try . you I know you will like the price ,the package, quality it is worth it. . I highly recommend it.

Wants on a screw it can be used several times
I like this so much better than Loctite. It doesn’t dry into a hard plastic. Because of its fibrous consistency, it actually stays pliable and you don’t have to reapply it every time you remove a screw. Big time saver. Stupid me forgot that I had already ordered one so now I have 2 ounces of it enough to last a lifetime.

Holds nuts and bolts really well.
Have used Blue Thread Locker for over 40 years; it holds bolts and releases easily when you need to remove them.
