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.
I’ve always thought this too. I understand clockwise/anticlockwise and the direction being defined from the top - but it’s a circle - no matter which way you turn, it spends 50% of the time going either direction. The phrase works with screwdrivers (especially ratcheting ones), but not so much spanners or Hex Keys IMO.
I always railed against this. I’m using clockwise-lockwise from now on.
Agreed. If the screw moves left or right, it fell out of its hole, lol. I guess “clockwise” is hard to rhyme.
If you mime tightening a bolt, your thumb moves to the right. And vise versa.
Left or right-handed?
Both. Odd that you would ask without trying it yourself.
With my left hand, my thumb starts facing right, and then sort of goes down and towards the left.
Am i weird if i tighten bolts by moving my fingers up/down intsead of side to side?
Nah I do the same till it’s loose, it’s faster to rotate with minimal rotation. But once it get harder then I do slower but larger rotations with thumb starting from left side and goes towards right for like 120°.
I explained here, but that’s why I prefer using the right-hand-rule. Sometimes thinking about clockwise in strange frame of references hurts my little brain.
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.
