Permatex Blue Threadlocker

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.

Great product. Works perfectly.

Used in applications where regular Loctite wou!d drip and be a mess. I squeezed a small amount out on a clean disposable surface and literally applied it with a toothpick and that worked we in the confined workspace that I was in. I have used as directed as well. I have used Loctite for decades and always keep blue, red and purple in my shop.

I tried the Permatex 24010 Medium Strength Threadlocker, and wow, it’s like magic for screws! When I used it, I couldn’t believe how well it kept everything in place. I was helping my dad fix some stuff, and we put a little bit of the threadlocker on the screws before we screwed them in, and they didn’t move at all! It’s like the screws turned into superheroes that can’t be defeated. It’s really easy to use too! I just put a tiny drop of the threadlocker on the screw threads, and then I tightened them. It didn’t make a mess, and the screws stayed nice and tight, even after we used the machine on them. I thought they might loosen up, but they stayed put! I think this threadlocker is the best because it’s super strong, but not too strong. You don’t need to use a lot, and it works just right. I don’t have to worry about my screws falling out anymore! It’s like a secret tool that makes everything stay in place.

Great threadlocker. Easy to apply.

Thread locker works the way it is supposed to and got it for a good price when I bought it.

Never lets fasteners become loose.

Works as advertised.
