Lock nuts; do they work?

[Mooseman]

This video came up on my feed and was quite interesting. Tests different types of lock washers, and nuts, and even double nutting.

Quite surprising.

Fixed. Also added part 2.

That channel has lots of little life hacks and tips for all sorts of things and most are short videos with no blah blah or fluff. Worth a sub.

Good stuff, I never knew how a split washer was supposed to function. Learned me something new today.
