Gas valves famously use the opposite direction

We have that in Gujarati "navde nokhu satde sajjad"

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.

DROL: Dicht Rechts, Open Links.

I think I just prefer Links Los, which implies that the other way tightens.

Dutch, BTW.

"Eins og kókflaska" or "Same as a Coca Cola bottle", not universal in Iceland though

I remember it as right hand screw rule

Gas pipes. All gas fittings are reversed threaded. So it is virtually impossible to connect one to the other.

If japanese has one, I've never heard it. Japanese wife hasn't either. She was surprised it's a thing. She said maybe tradesmen might, but certainly nothing everyone knows
