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?

A nice thought until you run into a left handed thread........
And you feel so incredibly dense every time you run into it and you can't figure out what's going on. The crank on my kids bike was out of whack the other week and I kept tightening it down and it kept coming back loose. I was turning the crank one way to tighten it which was pushing it against the lock nut but it needed to turn the other way to be pushed against the bearing before I tighten the lock nut down. If it was all right-handed it would have been clear what I was doing.
It's works most of them time unless you're in a specialty trade making spindle, gears, and such that must be threaded backwards to avoid the wheel undoing itself.
Or you work with gas cylinders.
I don't understand this one, please Airgas
Reverse threads on gas cylinders are (as far as I know) only used for flammables.
I was sure there was a reason, I just never worked in the field long enough to learn or ask why
Thanks ๐ซก
They're made that way so you don't accidentally connect a gas cylinder to a water line.
I'm Norwegian. I never learned a rule in my language and always just went by instinct. Until ~3rd year of university in physics where someone told me tha the right-hand-rule applies to screws. Now I use that everywhere for screws in strange positions.
Can you elaborate? I googled the right hand rule, but I'm not seeing how it applies to screws.
Well, this was a life-changing comment.
"La derecha oprime y la izquierda libera"
The right oppresses, the left liberates
La derecha oprime y la izquierda libera
I just knew that would be Spanish, without being able to speak more than a few words. It works far better than our effort and is both a sardonic and satirical political comment.
Well played Spanish if that really is the equivalent in common usage. Our effort sounds like it was invented by a young child whilst responding to a BBC quiz.
