Permatex Medium Strength Threadlocker Blue is the ultimate all-purpose solution for locking and sealing threaded fasteners to keep them secure, even under extreme conditions. Designed to prevent parts from loosening due to vibration, this versatile threadlocker bonds with precision, forming a durable, shock-resistant seal that withstands leaks, corrosion, and loosening. Ideal for nut and bolt applications sized 1/4 to 3/4 , Permatex Threadlocker Blue eliminates the need for costly lock nuts and washers while sealing threads completely, protecting them from rust and corrosion. Applied as a liquid or gel, this medium-strength threadlock is perfect for automotive and household applications, from valve cover bolts to water pump and drive shaft bolts. Unlike permanent threadlockers, this formula provides strong adhesion yet allows easy disassembly with hand tools, making maintenance and adjustments simple. Whether youre working on your car, bike, or home project, Permatex Medium Strength Threadlocker Blue delivers unmatched reliability, sealing power, and convenience to keep every job secure.
I bought this for some furniture assembly after noticing my screws were coming loose. The Permatex Threadlocker Blue worked just right. It’s easy to use and applies smoothly. I appreciate that it's not permanent either—very handy!

Arrived damaged, but product is okay
The tube was slightly dented when it arrived, which worried me, but thankfully the thread locker itself worked fine. I used it on some nuts and bolts around the house, and it did prevent loosening as promised. Just wish the packaging was better!

Not as strong as I hoped
I had high hopes for this thread locker, but it didn't hold up as expected on my outdoor patio furniture. While it worked initially, some screws still came loose after a couple of rainstorms. Might be better for indoor use.

Works well, but be careful with application
The medium strength of this Threadlocker is just right for most household tasks. I found it very effective, but I accidentally used too much on one bolt and it didn't fit properly afterward. Just be cautious with the amount you apply!
