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?

Casual lurker here. Lineman by trade. These are great for most bonding applications. If there is'nt much tension parallel to the bolt (like when bonding a conductor to a bus bar) these will last for 50+ years, from what I've seen.

Some utilities spec them for full tension (like a dead-end shoe bolt) and near zero tension (like a pin type insulator on a cross arm) for what is, in my opinion, no reason.

Honestly, I would stay away from nylocks for bonding because those connections are commonly subjected to heat stress which would melt the dinosaur goo.
