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?

Never heard of that. When attending a trade school there was never the necessity of a mnemotechnic to know in which direction turn the tool.
As other mentioned this kind of phrase is useless if you are in the opposite side.
What I always heard is “la regla del destornillador” (the screwdriver rule), as a substitute for the right hand rule.
