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?

The assumption in this whole post is that it's right-thread, since left is so uncommon.

Most common example would be a bicycle, I think - your pedals tighten on "in the same direction the wheel turns" as you look at them. So your left pedal has left-hand thread, and goes on and comes off backwards.

The effect of precession also means that you can tighten the pedals on finger tight and a good long ride will make them absolutely solid - need to bounce up and down on a spanner to loosen them.
