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 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.
In finnish also same but just replace sun with day. No idea about plumbing though.
The reversed rule in plumbing is only for gas lines in the Netherlands.
In the plumbing sector, left-hand threads are used whenever two pipe ends need to be connected that cannot be rotated. The connector is then equipped with a left-hand and right-hand thread and can therefore easily be screwed between them.
So it’s not just typical for Nordic countries, but depends on the application.
I could give you an example. In my kitchen we have a faucet with a detachable aerator. We detach it when we want to use a attachment for a garden hose. When attaching the aerator or the garden hose attachment, the threads are reversed. I might be wrong, but two opposing threads shouldn’t be able to screw into one another right?
Whut. Chaged my bathroom sink not long ago and it definitely loosens to the left/counter clock. Norway.
Let’s start saying “rajtan-tajtan” as some weird anglicism?
Hahaha thats brilliant
