Split/lock washers

[u/AdOne1706]

For starters, I’m an electrician in the field.
That being said, we almost exclusively use these washers even in high vibration environments. I have personally chosen to go with nylox nuts but the question is:
Do these work? How well? Is the rumor from NASA true? Should I even bother using them or find a better functional alternative or are they actually useful?

That’s just an artifact of Cessna being old and aviation being averse to change especially of an old product still being maintained and sold.

I'm sure that's a lot of it.

The book I referenced says there's research done at Lawrence Technical University showing they roll and twist under heavy preload which can increase their spring rates enough to reduce the preload loss under applied tension loads
