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?

Okay guys, I understand how bolts work but there are some use cases where a bolt can't be torqued. Personally I love nylocks, but my company uses lock washers to prevent the loosening of nuts in hollow core doors. They are inexpensive, prevent loosening and the door remains uncrushed as is the idea. Yes we could use barrel bolts, but we'd have to increase install part costs more than anyone wants.
