Great for small fasteners!
I usually use blue loctite, but I had some trouble with smaller fasteners stripping so I figured I would try this. It works great! Gives just the right amount of hold to keep screws from backing out and they’re easily removed with a tool.

Reliable Threadlocker for Securing Aluminum Parts
he Loctite 222 Threadlocker for Automotive (High-Temperature, Low-Strength, Anaerobic, One-Piece Assembly, Non-Corrosive, Purple, 6 ml Tube) has proven to be indispensable for my projects, especially when it comes to securing screws on aluminum parts. Given that many stores nearby do not carry this specific Loctite product, I was pleased to find it online. As with all Loctite products, it worked exactly as described. The low-strength formula is perfect for applications where easy disassembly is required, yet it still provides enough hold to keep screws securely in place under high temperatures and vibrations. The non-corrosive nature of the threadlocker also ensures that it does not damage the metal surfaces, maintaining the integrity of the components. For anyone needing a reliable threadlocker for automotive applications, especially on aluminum parts, I highly recommend the Loctite 222. It’s a trustworthy and effective solution for locking and sealing screws. 🚗🔩🛠️

This tiny tube saves my projects
This little purple tube is for my husbands RC car hobby and the kids bike repairs. I use it on those tiny screws that love to wiggle loose. Just a dot and they stay put but i can still undo them with a normal tool. Im glad the tube is small because it fits right in our junk drawer.

Good stuff
I use a lot of the Loctite 242 variant for various projects and thought I would get this variant for a 3D printer build I am doing. So far it's working great and I will purchase more. I was going to purchase a large bottle of this but it seems there are a lot of phony versions of this on Amazon in the large size, so I purchased the small size and it seems to be the real deal and seems to work like it's supposed to.

Perfect low strength thread locker for use on tiny parts like watch bracelet screw pins.
I keep several different grades of Loctite thread sealer. The 222 low strength purple Loctite is perfect for small parts that you want to be able to loosen in the future. It is the perfect strength for threaded watch bracelet pins. It keeps the pins from loosening and backing out but it is not so strong that the screw heads are stripped when trying to remove the bracelet pins in the future. With parts that are that small, even medium strength Loctite 242 is too strong and requires fairly substantial heat to loosen without stripping screw heads. The 222 is the perfect solution in those cases.

Made in Mexico.
Genuine and quality product. Works as it should. Couldn’t find any loctite locally other than made in China ones. I’m glad Amazon stock this!
