Loctite glue is an important element in a solid multirotor build. Also known as thread locker, Loctite is used to fix and lock threaded fasteners in place. Here I will share some information about this type of glue and how best to use it.
Where to buy?
So What is Loctite?
Loctite is the brand name of an adhesive product. This type of products is also known as “thread-locker”.
Loctite is often used on motor screws, which helps prevent nuts and screws from loosening over time due to vibration. When it’s cured the screw or nuts will become harder to remove.
Loctite isn’t like normal glue, It feels more like oil. Remember that It takes a while to dry/cure after applying.
How to use Loctite?
You only need to put a tiny drop at the end of the 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 is recommended 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.
Cheap and Last Forever!
I have been using this small bottle of the Thread Locker TL242 for about 4 years now, I am getting great results and there is still about half of a bottle left.
Did I mention the bottle only costed me $1 ?! It’s truly a must-have tool when building a quadcopter!
