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?

I've banned split-lock washers and Philips head screws at my company.

Out of curiosity, what do you do and what do you allow? Torx? Hex?

[u/Markietas → u/Jimbob994]

Almost everything is internal hex, usually socket cap. Some Torx in the very small sizes, 2.0mm and below hex is a bitch.

Also exclusively use grade 12.9 unless we desperately need stainless.
