Bolt Threadlocker

Do I Need Threadlocker? By far, the best reason to use a threadlocker solution is to prevent the accidental back off of fastener assemblies due to vibration. While not necessary in all applications, solutions can also be used any time a nut and bolt are placed together.

What is the difference between Blue and red Loctite?

Well let's clear this up really quickly for you: Blue loctite threadlocker is for using on fasteners that you want to unscrew easily. Red loctite is for a more permanent fix, on parts that you won't be loosening for years to come.

When should you not use Loctite?

Loctite can't fix a worn-out bolt. You should replace all bolts and nuts that have sloppy threads. For a proper hold, a bolt needs three complete revolutions of threads to be filled with the fluid. Two drops of threadlock is usually enough on 6mm and 8mm threads.
