Does each language have "lefty loosey righty tighty"?
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.
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.
