This threadlocker works exactly as it should.

Whether for small screws or larger fasteners, it performs great every time.Reliable, strong, and a must-have in any toolbox. Highly recommend!

’ve used Loctite Blue 242 on everything from motorcycle parts to furniture, and it works exactly as advertised. It keeps screws and bolts from vibrating loose, especially on items that see a lot of movement or stress. What I really appreciate is that it’s strong enough to hold, but not so permanent that you can’t remove the fastener later if needed.The application is easy — just a drop on clean threads before tightening, and you're good to go. It sets up nicely and doesn’t make a mess. I’ve had zero issues with rust or corrosion after use, and the bottle has lasted me a long time.Definitely recommend this for anyone who works on machines, tools, or even around the house. Just be sure you’re using it on parts you might want to remove later — this isn't the red (permanent) stuff!

I purchased this Loctite primarily to secure the optic on my home defense firearm, and it has performed flawlessly. After multiple range sessions and hundreds of rounds fired, my optic hasn't shown even the slightest bit of movement - exactly what I needed for a critical application where reliability is paramount.The product proved so effective that I started using it for household repairs too. Those annoying, constantly-loosening ceiling fan screws that created a shaky noise? Completely silenced after application. The medium-strength formula seems perfect - strong enough to keep things secure, but still allows for disassembly when needed with standard tools.Application was simple with the precise nozzle, and a little goes a long way. I appreciate that it dries clear and doesn't leave messy residue. For anyone needing to secure screws in firearms, machinery, or household items, this Loctite delivers professional-grade results.For those using it for firearm related screws: Always follow manufacturer instructions for firearm applications and allow proper cure time before use.

Dries Quickly. Seals well. Sticks the bolts down. Easy to use and doesn't make a mess. Heat Resistant.

Must have product for small screws and moving parts that you dont want to lose. Especially useful with firearms for installing sights and other items that need the small screws and what not retained. It is extremely useful and definitely worth the price. It is easy to apply with the dripper style tube. Does not take much especially of the red so this tube should last quite a bit for most people as I bought a tube years ago, use it quite often and still have some left that will last me a long while

Worked well to secure screws on scope rings. Quick arrival and good value on Amazon.

Why did you pick this product vs others?:Good , I used this on a bolt on my motorcycle thatkept coming loose, it is staying in place.

Always dislike how small it is. It’s hard to grasp and there is so little in it. Once you start to use it, it’s very fluid and beings to drip everywhere. Fairly annoying.Either way, the loctite is a great product. Nice that it’s not permanent.
