Also transparent nail schellac works. One drop on the hole, screw in, let it cure. Done.
When you have to remove it, the schellac breaks free.

It's nice to know I am not the only one who needs hours/days to repair a 1 second mistake.

Let me just say this, because I ran into this problem and destroyed an equipment.

The said equipment didn't have a lose hole but all screw holes are tapped directly into aluminum case itself.  That meant, occasionally, metal dust or small shaving may be generated.  One of them got on my circuit board which had VERY fine pitch SMD components.  Then it proceeded to short out the pins.  When one landed on CPU chip (SMD) then it killed the IC.  I could see the aluminum dust and tell-tale sign of damage under microscope.

Since then, I blow dust very carefully before closing the case.  But there is nothing I can do about the dust generated DURING rescrewing of the lid.

If you use any conductive material to fix the screws, I'd be careful about this....

So use some loktite thread locker (red or blue liquid) on the screw. This should bind to the particles and keep them in place
