Reliable Fix for Loose Bolts and Screws

Everyday ReviewsSeptember 3, 2025✓ Verified purchase

Reliable Fix for Loose Bolts and Screws I’ve been using Permatex 24200 Threadlocker Blue on a few small projects around the house and in the garage, and it’s been a dependable problem-solver. This medium-strength formula is just right for fasteners that tend to work themselves loose over time—things like cabinet screws, lawn equipment bolts, and even some car parts. It keeps everything snug without making disassembly a nightmare later on. Application is straightforward: just a small drop on clean threads before tightening, and it sets up quickly. I like that it helps protect against rust and corrosion too, which is a nice bonus for anything exposed to moisture or vibration. Best of all, I’ve had no issues removing treated fasteners with regular hand tools when I’ve needed to—no stripped bolts, no headaches. The tube is small (6 ml), but a little goes a long way. Unless you’re tackling a huge project, one tube should last quite a while. Bottom line: A reliable, easy-to-use threadlocker that does exactly what it promises—keeps fasteners secure but still removable. Read more

Just the right amount of locking strength

ILoveTechMarch 26, 2023✓ Verified purchase

I can confidently say that this product is an excellent choice for anyone in need of a reliable and easy-to-use threadlocker solution. One of the things I love about this product is its medium strength. It provides just the right amount of locking strength for a wide range of applications, from automotive repairs to household projects. It's not too weak that it will come loose, but also not too strong that it will be difficult to disassemble in the future. The blue color of the threadlocker makes it easy to see where it has been applied, which is especially helpful for ensuring that all areas have been covered. I also appreciate the fact that it comes in a 6 ml bottle, which is a convenient size for both small and large projects. The application process of this threadlocker is very straightforward. Simply apply a small amount to the threads and let it dry. The threadlocker dries quickly, and I have never had any issues with it dripping or running. One of the things I appreciate the most about this product is its reliability. Once it is applied, I know that my threads will stay securely locked in place, even under high levels of stress or vibration. This provides me with peace of mind knowing that my repairs or projects will be sturdy and long-lasting. Overall, I would highly recommend this threadlock to anyone in need of a reliable and easy-to-use threadlocker solution. It provides just the right amount of locking strength, is easy to apply, and dries quickly. It's a must-have in any toolkit. Read more
