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?

I can't think of an equivalent phrase in Bulgarian for that, but it's known that [most] threads tighten when turning clockwise... and if you don't know what direction the clock goes, what are you even doing with screws or bolts...
And again there are special cases even outside of threads - for example in plumbing there are some valves that are open when the handle is parallel to the pipe and closed when the handle is perpendicular - and it might just happen that the closing motion happens counterclockwise.
reverse threads are also found on things like bicycles and cars which have parts that spin counter clockwise
Yep, I'm familiar with those - on almost any bycicle the left pedal would tighten to the crank counterclockwise.
Except for the stupid friggin discount stationary bike my wife bought. That must be the exception you're referring to...
That's why it's discounted...
