Loctite thread-lock is often used on motor screws in a quadcopter build. It helps prevent screws from loosening over time due to vibration. When it’s cured, the screw or nut will become much harder to remove (but not impossible!)

Loctite take approximately 2-3 hours to dry and cure.

  • Particularly suitable for less active surfaces e.g. stainless steel
  • Prevents loosening through vibration and leakage of threaded fasteners

How to use Loctite

You only need to put a tiny drop at the end of a screw, on the thread, before fastening. Don’t use too much or you might have a hard time removing that screw later, and using too little will lack the desired strength.

Loctite glue should be applied at the tip of the screw, this assures full and even coverage over the length of the thread during installation. For best result and full strength, it’s best to remove the bolt or nut and clean all the contact surfaces before applying Loctite glue.

Note that thread locker only works on all metals, such as steel and aluminium, but not on non-metal such as plastic or nylon.
