But why does the bolt go up and not down?

[@LieseFury]

i'm just guessing but maybe because the vibration is weaker farther away from the motor.

[@iout]

My guess is that most vibrator motors are just unbalanced weights rotating in a circle. That means that when the motor spins, it is actually transferring some of its rotational momentum into the bolt in a periodic manner that only amplifies as you go up the screw. And probably aided by some fairly loose tolerances in the nut, if you spin the motor in one direction it can shake the nut off the screw by further imparting that rotational momentum into the nut.

[@EebstertheGreat]

The bolt isn't just translating in space but also rotating. Whenever it rotates along an axis not through the bolt's center, the end will sway and apply a tangential force to the nut. If you think about this as being similar to circular motion, then in the rotating reference frame, this looks like a centrifugal force away from the head of the bolt. In other words, imagine you had a brass ring sliding on a rod, and you swung the rod around. The brass ring would fly off the end.

@@name-n9j9j There is a vibrating motor in the head, the same kind of thing they put in a phone. It's a gimmick. The nut goes up not down for the reason I already gave. It's just because the head of the bolt is being held still, but the other end is not. So it sways around and throws the nut off.

But the bolt down side
