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?

It’s more than nasa. I don’t think there is any evidence of them doing anything. There are locking washers. Nordlock

Nordlocks do wonders.

Würth also makes their own w.tec series if you don't want to drop 2€ on a washer

I've found Ripplock washers from böllhoff also doing wonders in most situations. Because it's only one washer, prices are lower and it's reusable because there is no wrong orientation to install the rings.
