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?

"La derecha oprime y la izquierda libera"

The right oppresses, the left liberates

[-] ILikeTraaaains@lemmy.world 1 points 8 hours ago

Never heard of that. When attending a trade school there was never the necessity of a mnemotechnic to know in which direction turn the tool.

As other mentioned this kind of phrase is useless if you are in the opposite side.

What I always heard is “la regla del destornillador” (the screwdriver rule), as a substitute for the right hand rule.

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.

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.

I'm indian and learns right hand screw rule in high school physics

[-] kamen@lemmy.world 1 points 11 hours ago

I've heard the right hand rule regarding magnetism and current direction (because it's useful to illustrate correlation between vectors), but never about screws. Now that I think of it, it makes perfect sense there too, only that you have to imagine a thumb pointing down most of the time...

[-] bad_alloc@lemmy.dbzer0.com 18 points 21 hours ago

Well, this was a life-changing comment.

[-] KrankyKong@lemmy.world 6 points 17 hours ago

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

[-] OminousOrange@lemmy.ca 7 points 17 hours ago

Right hand rule applied to torque.

A nice thought until you run into a left handed thread........

[-] LifeOfChance@lemmy.world 22 points 19 hours ago

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.

[-] CertifiedBlackGuy@lemmy.world 6 points 18 hours ago

Or you work with gas cylinders.

I don't understand this one, please Airgas

[-] Cyteseer@lemmy.world 9 points 16 hours ago

Reverse threads on gas cylinders are (as far as I know) only used for flammables.

[-] CertifiedBlackGuy@lemmy.world 5 points 16 hours ago

I was sure there was a reason, I just never worked in the field long enough to learn or ask why

Thanks 🫡

[-] NoSpotOfGround@lemmy.world 9 points 15 hours ago

They're made that way so you don't accidentally connect a gas cylinder to a water line.

[-] Death_Equity@lemmy.world 12 points 15 hours ago

Fucking facists keeping me from tap en flambé; like they know what is safe.

You know this has always confused the fuck out of me. You are going around a circle, how is there left and right? There is up-and-left, down-and-left, either way is left. If I am starting on the right of the circle (assuming I'm looking at it) which way is right? Up or down?

[-] angrystego@lemmy.world 7 points 14 hours ago

The starting point is on the top.

[-] Sludgeyy@lemmy.world 17 points 18 hours ago* (last edited 18 hours ago)

Imagine it like a car steering wheel.

You'd say turning the wheel to the right turns the car right.

Think of it like this. Like your hand is holding on the top of the steering wheel.

[-] Cataphract@lemmy.ml 8 points 16 hours ago

ok but what is behind this picture? I see fur and old matted flesh? a paw with no nails or an old dogs snout?!?!

[-] MelodiousFunk@slrpnk.net 8 points 15 hours ago

It's better to not ask questions sometimes.

backs away slowly

[-] mexicancartel@lemmy.dbzer0.com 1 points 10 hours ago

Use right hand thumb rule. There is no right, there is no left, there is no clockwise or anticlockwise. All of them depend on the way you looks. Rught hand thumb rule fixes it for humans

Finnish doesn't have one. We just learn it by instinct and use the time saved to warm up the sauna.

I'm from back in the generation when we had volume knobs.

My dad told me turn the volume up to tighten it, turn it down to loosen it.

I've never had a problem.

[-] 418_im_a_teapot@sh.itjust.works 38 points 1 day ago* (last edited 15 hours ago)

This phrase has never made any sense to me. It’s a circle. If one side is moving right, then the opposite side is moving left. So the phrase only makes sense if you specify which side we are talking about, which nobody ever does. Therefore it’s completely illogical to me while everyone else just gets it. Side note: Autism can be a real bitch sometimes.

Edit:

Some people don’t understand how I can see a problem. That’s cool, but don’t be a dick. We all look at the world through different lenses.
This is when I was a kid “helping” my grandfather in the garage. I’m older now and understand that “righty tighty” references the top of the rotation.
Some people rotate their perspective 90° and imagine themselves standing on the screw. Therefore when your face rotates to the right the screw is tightened. I hadn’t ever thought of that. But I had imagined rotating my perspective 90° the other direction –the top of my head as a screwdriver. In that case, “lefty tighty”

The Spanish version is my favourite: la derecha oprime y la izquierda libera (the right oppresses and the left liberates)
