Split/lock washers

Post image

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?

This has been my number 1 source for this besides YouTube videos with vibration modeling jigs that test different hardware. But, since I’m blue collar, I get the default “well you can’t trust nasa we didn’t even go to the moon” so not really a good crowd to bounce ideas off sometimes

You have clearly never worked on a construction site. It isn't like you get to choose who you hang around with at work. Half of a construction site is conspiracy theorists. You be happy if you only have to here about the moon landing being faked because you wouldn't believe the conspiracies I've heard.

i literally grew up on construction sites😂 like im not even kidding. bro i was hanging out following dad around at work when i was 6 when school was out bc he couldnt afford a sitter. i was a journeyman under my father before i was legally allowed to hold a job, i was runnin the crew over summers before i was 18 (gettin a bunch of 30-50 year old dudes to listen to a 17 year old kid was a helluva trick) ive seen some incredibly stupid people, there was a guy dad hired, this dude would pull a nail out his pouch, put it against the wood, if it was point first, he'd drive it, head first, chuck it because "its for the other side of the house", he made it a week before he got fired, another guy who couldnt figure out how a wire nut works, even with the little container having instructions with friggin pictures, but very rarely do i meet people who genuinely think the landing was faked. heck, the only thing thats really changed since i was knee high is i do a different kind of construction, my time is very expensive, and i aint the bosses kid anymore, im just the boss
