We have that in Gujarati "navde nokhu satde sajjad"

Nope. Polish doesn't have one.

We have: "Nach fest kommt ab"

The phrase "Nach fest kommt ab" is a German saying that translates to "After tight comes off" in English. It's typically used to describe the idea that if you tighten something too much (like a screw), it will eventually break or come loose. It’s often used to remind people to not overdo things.

Probably a result of turning wrenches since I was first able, but that rule, to me, feels akin to "up the stairs take you up, down the stairs take you down".

I remember it as right hand screw rule

I don't think we have a Swedish one. But we call clockwise "medsols" and counterclockwise "motsols". Meaning "with the sun" or "against the sun" Does everyone have reversed threads on plumbing or is that a Nordic/Swedish thing? All plumbing has the reversed rule, left tightens and right loosens.
