4 Pack Thread Locker Blue 242 and Red Threadlocker 271, Nuts & Bolts Locker Lock Tight & Seal Fasteners Thread Locking Compound Anaerobic Curing Metal Glue (242/271)

I like the size of these tubes, they are small enough that you don’t have to worry about them drying up before you can use them.Great for any kind of mechanical work where you want to make sure bolts stay tight.

I have received items as describe, nice items, fast shipping.Thanks and regards.

Works exactly as advertised it does what it’s supposed to

Has a strong hold. There was less in the tube than I thought there would be, but pretty sure the volume was correct.

Came as stated. Happy with this purchase.

I ordered this because it was the perfect combination I was looking for, unfortunately, when I received the box I noticed the outside of the box was slimy and sticky. Upon opening, it was apparent why - both of the caps on the blue tubes were almost completely off resulting in their entire contents leaking out all over the inside and outside of the box. They were basically empty. No worries, it happens sometimes - I put in for a replacement and received that one and noticed the box felt a bit light. Imagine my surprise when I opened it to find that it only had the two tubes of red! It seems like I don’t have any luck getting the blue that I really needed.

The directions say this will cure in 4 minutes and achieve full strength in 24 hours. I thoroughly cleaned the threads with brake cleaner, applied a few drops and assembled. Then waited 8 minutes, twice the time, but I was able to unscrew my part because the product was still wet and uncured. I immediately put it back together and waited 24 hours. Presumably all is ok, but I don't know how strong if I can't trust the directions to be correct about the 4-minute initial cure. I will update this review if the bond fails for whatever reason.EDIT: The one-star reviews complaining about the bottle half full are hilarious. First, you're buying a certain amount of ounces/grams of product so who cares if you get a large bottle as long as you get the correct amount of liquid. Secondly, this adhesive is anaerobic, meaning that it cures when you take away the oxygen, therefore if the container was filled to the top, it would harden in the bottle. The listing clearly says that it must be shipped half filled with air in the container to prevent it from curing in the bottle.EDIT 2: Failed after only a few hours. I do not believe my parts exceeded the rated 482 F of heat. I cleaned the threads and tried again.

Great 👍
