Does each language have "lefty loosey righty tighty"? (lemmy.world)

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?

Can you elaborate? I googled the right hand rule, but I'm not seeing how it applies to screws.

Grab around a screw with your right hand and extend your thumb (like a thumbs up). Then rotating the screw in the direction which your fingers are pointing will result in the screw moving in the direction your thumb is pointing.

Thumbs up for lifting the screw upwards, thumbs down for screwing the screw downwards. And you can move your hand around to figure out screwing directions for any tricky spots.

Beware the left handed screws, they're around but rare. My last encounter was inside a vacuum cleaner motor assembly.

Propane and propane accessories also use left-handed threading. It can be really weird to get used to after a lifetime of righty tighty.

Great explanation, thanks
