Convenient Loctite Threadlocker Stick for Easy Application
This Loctite Threadlocker Stick is a game-changer when it comes to securing bolts and screws in place. It's so easy to use - just twist it up like a glue stick and apply directly to the threads. No more messy liquid dripping everywhere! The medium strength formula holds everything tight without making it impossible to remove later if needed. One thing to note is that the stick format can make it a bit tricky to reach tight spaces or apply evenly on smaller screws. However, the convenience and mess-free application definitely outweigh this minor inconvenience. Overall, if you're tired of dealing with runny liquids and want a cleaner threadlocking experience, this stick is worth a try!

The Perfect Solution for Easy and Mess-Free Application
I absolutely love my Loctite lipstick! It's like gold for mechanics, offering a convenient way to get the job done without the hassle of shaking old bottles. With this product, there's no mess or worries about it tipping over. It lasts just as long, if not longer, than the small bottles, making it perfect for those awkward jobs. Highly recommend it for anyone looking for a reliable and efficient solution.

So much easier to use than the bottle
I used this when reassembling pocket knives. The little screws get a tiny bit on the threads and the cap is popped back on. No more leaky bottle where I have to put a drop on something and then carefully dip the tiny screw into the wet and then not have it run everywhere. So much easier to use and control with the paste like consistency. Since I use so little the stick will probably expire before I ever use it but I will replace it with the same thing again. Wish I had known this existed years ago or whenever it was released.
