yes, I can confirm this by own experience! It may take some time, but eventually it will happen.

Another method to prevent unscrewing is the use of a piece of thin sheet metal with a hole suitable for the thread bolt and shaped in a form so it can't rotate around the bolt. Impose it over the thread bold to come beneath the nut and after tightening the nut bend one free section of the protuding sheet metal sharp upwards along one suitable edge of the nut.

Kind regards

1,With a thin saw cut halfway through the side of the nut then gently crush it in a vice,producing a locknut,

2,put a small drop of nail polish on the thread.
