Liqui Moly Threadlocker 3801 (medium strength) (10 g)

Liqui Moly Threadlocker 3801 medium strength 10 g for secure threaded connections

When screws slowly loosen due to vibrations, it eventually gets annoying. That’s exactly what Liqui Moly Threadlocker 3801 is made for. You use it for securing and sealing threaded connections, specifically where the connection should later be dismantled with normal hand tools. Medium strength simply means: holds reliably, but remains manageable when service is needed.

The threadlocker cures in the absence of air, i.e. directly between closely fitting metal surfaces. This significantly slows down self-loosening and at the same time reduces leaks that can otherwise be caused by shocks and vibrations. Sounds simple, and in everyday use it is. Apply, tighten, done.

Application: Securing and sealing without unnecessary compromises

You apply the threadlocker to the thread, assemble the parts, and let the material do its job where it belongs. Curing starts as soon as no more oxygen can reach it. That’s practical, because it doesn’t harden already on the tip or on the thread “in the air”, but only in the joint. And yes, that’s exactly the point, especially with metal-to-metal contact.

What we like about the 3801 is that it doesn’t overdo it. It prevents loosening, helps with sealing, and stays in the medium strength class. For many repairs and assemblies, that’s exactly the pleasant middle ground: not too weak, not unnecessarily brutal.

Who it makes sense for and when you should use it

If you’re working on vehicles, machines, brackets, or ordinary metal constructions, you know the game: at first everything sits tight, later the connection starts to work. With the medium-strength threadlocker, you counteract that without ruining later disassembly for yourself. It’s suitable for common bolts and nuts in different sizes and strength classes, so not just for a special case.

And the temperature range from -60 to +150 °C is chosen so that you can also use it where it can get cold or where heat is simply part of operation. In short: a small 10 g tube that quickly becomes a habit in the workshop.
