Game changer!
[This review was collected as part of a promotion.] I love this loctite threadlocker! I use it on all my builds and projects. This is my go to and keeps things snug and right where I want them. Only time I don't use it is high heat situations. I really like it because it holds well but you can still break it with enough juice if you need to.

    If you want it to stay tight and not loosen up until you are ready to loosen it. Then blue 242 is the one for youMake sure you read All of the instructions before using and you should be good to go.

    Thank you for choosing Loctite for your project.
      Tested time and time again
      [This review was collected as part of a promotion.] I've been been using Loctite for many years for various things. The Threadlocker Blue 242 did not disappoint. I like that the tube itself is small enough to handle for small projects like this. I also like that it's blue and super easy to see when applying to the screw. My best advice is to make sure to leave it to "cure" for a day or so. I really think that has been the best trick.

          blue loctite
          [This review was collected as part of a promotion.] I have been using blue threadlock for years. I collect pocketknives and take them apart to clean. Putting them back together you can count on the screws backing out of the pocketclip. A failed pocketclip is a lost knife. This stuff helps secure the screws when I reassemble so I no longer lose knives.

            Good!
            [This review was collected as part of a promotion.] I would choose the brand anyway of the week for my glue needs. It’s easy to use. You can recline and use again (not like some others). And it really super holds everything in place. Could not ask for a better product! Choose this one when you need to fix things around the house.

              A must for bolts
              [This review was collected as part of a promotion.] We use threadlocker alot at my house. This is an amazing product. It allows your bolts to be tight and lessens the chance of turning or pushing back out. This thread locker is blue it's such a huge help so you know where it was applied! The tube seems small but it goes a very long way.

                    Great product
                    [This review was collected as part of a promotion.] Blue Loctite is awesome. It has an almost water like consistency straight out of the bottle. It only dries when there is a lack of oxygen, so when you screw metal on metal with Loctite coating the screw, you have time to wipe off excess. This also prevents moving parts from being affected by the Loctite as well. Overall, great product, It indeed locks threads.

                      The OG Threadlocker!
                      [This review was collected as part of a promotion.] I'm rebuilding an old Squarebody pickup and I couldn't do it without the peace-of-mind you get from using THe Loctite Threadlocker Blue 242. This really keeps any screws or bols from loosening over time. You just dab a little on and tighten it on down. It seems like it fills the gaps inbetween the threads and really keeps it tight. Highly recommended if you want something to not come apart!

                          Solid Hold and Works as described!
                          [This review was collected as part of a promotion.] Been using Loctite Blue for many years and the quality has remained excellent at all times. I use it on various firearm components and have confidence that nothing will back out due to recoil vibrations. Product releases when told to do so. Heat isn’t required but gentle heat helps break free. Not a permanent threadlocker.

                            [This review was collected as part of a promotion.] I personally used this on home gym equipment and it worked like a charm! Application is simple because a little goes a long way and it provides great security once cured. I’m a big fan and definitely recommend it!

                              Excellent Product
                              [This review was collected as part of a promotion.] I got this for my husband to fix somethings around the house. He said this is one of the best products that he has worked with. He was impressed with the fact that after he used it he was still able to remove it to reset it with a different part for a tighter fit. Also adhered to the screw well without any leakage or drippings.

                                Amazing thread locker, very helpful
                                [This review was collected as part of a promotion.] To me this is a must have if you do your own mechanical work, or build things your self, this helps keep bolts and other parts in tack from being vibrated out or becoming loose, all you need is a drop on the on the thread before you put it in and it can help it stay from finding a way out by itself, definitely helpful and doesn't work like glue so you can still get it out if needed, work great on my car

                                      [This review was collected as part of a promotion.] This Loctite - 0.2 fl. oz. Threadlocker Blue 242 works really great and actually holds very well and for a long time. It works better than any other glue or resin I’ve tried and it will e míen hold some weight as well. It dried quickly and didn’t leave a horrible smell. I recommend this to anyone looking for a really great adhesive.

                                        Holds tight!
                                        [This review was collected as part of a promotion.] My husband used this on some screws for our boat seats that kept coming loose. It has worked great to hold the screws tight and keep everything secure. It is easy to use and doesn't make a big mess. This product is essential when using screws in metal.

                                          [This review was collected as part of a promotion.] You know what Loctite does. It does what it does and it does it well! Apply this to a fastener’s threads and it’s pretty much guaranteed not to back out! I use this regularly on the threads holding the handle on hydraulic ball valves that I use for work. The handles usually fall off without using loctite.

I used this and it works great. I don't have to keep stopping to tighten the screw. Makes the job get done faster.

                                                  [This review was collected as part of a promotion.] Thread locker blue is a very common product in our automotive shop. My husband will not start a rebuild job without knowing he has at least two tubes. It only takes a very small amount to keep those nuts and bolts from backing back out, but can be removed. As a mechanics wife, the worst fit throwing comes when he can’t find his thread locker blue. I have learned to buy extras. This product is amazing and holds up like a champ! Thanks Threadlockerblue!!!

You can’t go wrong with Loctite products and am continually impressed with everything I have used. This threadlocker blue is great for anyone who does maintenance or even homeowners. It doesn’t take much, but helps secure any screws, bolts, etc that you don’t want coming loose. Removable so getting some on your fingers or other places you don’t want it isn’t a problem, yet stays secure where you need it to. Extremely helpful!

IT does an excellent job of stopping fasteners from vibrating loose but not being so strong like red that you end up breaking things to get them to come loose. For me in most situations this is my go to thread locker.
