The world has a lot of different standards for a lot of things, but I have never heard of a place with the default screw thread direction being opposite.

So does each language have a fun mnemonic?

I never really got that one, because "left" vs "right" only works when you are looking at the top of the screw. At the bottom, left tightens, and right loosens. So the one I remember is "clockwise to close".

Edit: the image on the post is actually a good example. If I'm off the screen to the right holding the spanner, then from my perspective, "left" would tighten.

It works for screws, but as a kid, I was never sure if the clock on the wall should be visualized attached to the ceiling or on the floor when saying "clockwise". So I was always a bit hessitant on that.
