Blue vs Red Loctite Vibration Testing

[Rawnei]

Found this pretty interesting and fairly new video about vibration tests of no-loctite vs blue- vs red-loctite.

The test itself is called the Junker Test where they use heavy vibrations to see when a bolt loosens or shear (https://en.wikipedia.org/wiki/Junker_test).

Fairly relevant as we see more of these sort of problems popping up amongst our wheels where motor screws in particular come loose over time.

Here's the Junker Test again but with different type of washers:

There are some products on the market to battle this like for example Nord-Lock washers but it's very unlikely we will see those in our wheels from factory anytime soon.

Another excellent and interesting video on this subject:
