Traffic light umbrella does not close

I told you I can do it ... :p

... Cantilever umbrella ...

Aren't these cantilever umbrellas generally sensitive to wind and then sway a lot?

Yes, they are not perfect. But I don't want to invest more money than the approximately €100 for this (with the exception of the Monday screw) quite nice cheap umbrella, since this is only supposed to be a temporary solution anyway. In the long term, we want to cover the terrace in 2-3 years.

Thank you very much :) I can work with that. I would first have to buy such drills, hopefully they don't cost the earth. Unfortunately, I don't have a caliper either. The thing with the glue is an interesting idea. Of course, it's a bit hacky, but what would speak against it? Is there a case when you would want to remove the screw again? Otherwise, "forever" sounds good for now. :P

If you use nail polish, you can get the screw off again. If you then also use a screw with a hex head or Torx, you can apply more force when screwing it on.

If you use nail polish, you'll be able to get the screw open again. If you then use a screw with a hex head or Torx, you can apply more force when unscrewing.

So you would use a different screw than the one that came with it?
Would you be able to get something like that at the hardware store? I don't have one like that at home; it has a really strange thin thread.
With my layman's eye, I had assumed that the screw isn't the problem, but rather the thread. The neighbor said something about a "chip" causing it to be broken, but I didn't really understand what he meant.
