@stuxI know this happens, and yet it's a bit strange, now I think about it.The nut is rising, therefore gaining potential energy.I would've naively expected the vibration to increase the entropy of the system by tending to let the nut follow gravity, yet the nut progresses away from it.Does it matter which way the motor is turning, I wonder? I don't think I fully understand the mechanics here.š¤

@stux I find installing lock wire to be very meditative.

@stux That's why in some setups screws that have the opposite direction are being used...Alongside Locktite which increases friction and thus prevents vibration-based unscrewing...

I used my iPhone to video something being cut on the table saw, and the screws on my metallic small rig case came loose. Now I have some Loctite holding the replacement screws in place. @stux

@stux Something to think about when you're on a long international flight over the Pacific Ocean. So many little bolts and screws in a big airplane. Thousands of them. All critical. All vibrating for hours. All it takes is one. Just one.

@stux Friction is how the nut rises. The vibrations ratchet it up the thread.

@stux How similar is this mechanism to fasteners either loosening or tightening when thermally cycled?

@stux do lock nuts or other 'self tightening' nuts defeat this?

@stux this seems a bit inflammatory - not sure if this is true in all aircraft maintenance shops, but when I worked a summer on a flight line (helicopters, mostly) the critical nuts were secured with safety wire ties, for just that reason.https://nci.edu/2022/04/04/everything-you-need-to-know-about-safety-wire/#:~:text=Safety%20wire%20is%20a%20necessary,part%2C%20and%20then%20twisted%20again.

@stuxLooks like an engine mounting on my boat. 3 cylinder diesel will shake anything loose.
