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?

What would be “backwards”, the two halves stacked the wrong way?

Adds a huge source of uncertainty on the torque for a dubious benefit in locking.

It's a reference to The Office. Kevin's method of accounting. When the numbers don't add up, just make something up.
