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 of the thing you want to tighten/loose.

What I always heard is “la regla del destornillador” (the screwdriver rule), as a substitute for the right hand rule.

We say the same thing in Brazil, but in portuguese: “A direita oprime, a esquerda liberta.”
