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
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?
I always think about the direction that the top of the circle turns to apply left or right rotation, though I usually use muscle memory.
Clockwise = Righty
Or imagine a bottle cap instead of a screw… Muscle memory kicks in.
Thank you! Clockwise looking down at a bottlecap makes sense!
Finnish doesn’t have one. We just learn it by instinct and use the time saved to warm up the sauna.
Or we pretend to be opening a Koskenkorva bottle in whatever orientation the bolt is in.
Same for Denmark. Except instead of warming up the sauna, it creates time for another Tuborg.
Gas pipes. All gas fittings are reversed threaded. So it is virtually impossible to connect one to the other.
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.
I think it’s fairly parochial, and sounds quite infantile to me. Growing up (uk) we just used clockwise to tighten.
It doesn’t even bloody work, lefty tighty righty loosy is every bit as valid if the spanner is at the bottom.
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.
Clockwise and counterclockwise may be more intuitive for some people. Is the clock-hand (wrench) going forward in time, or backwards. But I don’t know of any quick rhyme for that
Don’t think about it in 3d space.
They mean is the wrench handle moving left from the 12 o’clock position or left from the 6 o’clock position. You would not believe how many people struggle with lefty righty because of start location.
I defer to clockwise and counter-clockwise (anti-clockwise in UK). Except for new gen that never learned analog clock stuggles with this concept also.
Then they encounter a Left Hand thread and the universe implodes
Shit, a standard thread feels natural to me, but a left hand thread still fucks my life up sometimes — trying to notice what’s going on before I strip it.
My grill can connect to those camping propane tanks, but it’s threaded opposite… gets me every time
I love how half the people in this thread are under-thinking it and don’t seem to understand they’re doing so. I wonder whether it’s a bit.
If you’re looking head on to the screw/nut/whatever then we’re talking about the top of the screw/but/whatever.
You can also imagine if the nut was actually a wheel. Which way would you spin it to make it roll left or right.
Confused the hell out of me at a young age. That’s how I came around to thinking of it
But the entire rotation is either clockwise (right) or counterclockwise (left). Ultimately, its just a helpful reminder which way to turn lol
Clockwise and counter-clockwise makes sense.
But when you say “right” it’s not clear which side of the circle is being referenced. If the top of the circle is moving to the right, the bottom is moving left at the same time. So the saying only makes sense when you specify that you’re talking about the top of the circle.
you have to have never seen a steering wheel to not understand which side of the circle is being referenced. it’s always the top. who would even reference anything else and why.
“turn it right”
“which part???”
“the middle of course, you absolute alien”
Because people get confused when there is no space for the wrench at the top, and they put the handle at the bottom and try to move the wrench left or right, not referencing the top of bolt.
Because they aren’t using the saying as a clokwise/counter clockwise reminder but as a flat out instruction.
Yes, it’s always the top side of the circle in this context, or you can think about how clock hands do go in a specific direction, because they’re a radius, not a circumference. There, now it’s cleared up for you.
The clock hands move right when at the top but left when at the bottom.
Imagine it as if it were a track you were driving around, which way would you turn the wheel?
It’s getting so convoluted at this point just knowing clockwise/anticlockwise is infinitely easier.
What the fuck are you talking about.
You’re either rotating the fastener to the right or the left.
It doesn’t matter what side you’re talking about, because you’re not moving one side of the fastener, you’re rotating the whole thing one direction or the other.
Clockwise just means something is rotating to the right.
If I ask you to turn around to the right, are you going to ask me what side of you I’m referencing?
Here is clockwise. One arrow is going to the right and one to the left.
I tend to agree but you could argue that from a perspective in the center of the rotation you’re turning to the right. Imagine standing in the center of those arrows.
The whole thing is rotating to the right, that’s what clockwise means. Clocks rotate to the right. One arrow is not pointing left, it’s pointing in the direction of rotation, which is to the right.
You think this arrow is pointing to the right, when it is clearly pointing up and to the left? Fascinating.
The bottom arrow is, definitionally, pointing left.
If I ask you to turn around to the right, are you going to ask me what side of you I’m referencing?
No, because humans have a pretty clear forward direction. Screws don’t. You say turn a screw to the right, do you mean make the top of the screw move right or the bottom move right?
Most people assume the top, but not all, and the language is ambiguous.
You aee assuming a top orientation moving to the right. Give somebody a wrench handle at the bottom of nut and tell them left to loosen, you will see how most take it literally and move handle to the left side of their body. they think in terms of their left and their right, not the screws right left from a starting location at top, or if from 4 oclock position to the “left of” 4 oclock as if you were facing the 4.
I agree but there is a intuitive way once you are holding it. I remember looking at a car wheel and the signal lever not understanding how do people decided that up on the lever means right. Yeah it’s connected to the wheel rotation but why turning the wheel clockwise means turning right? When I actually sat on the driver seat there was an instinct.For most people It’s more logical to look at the “top” of the circle and corelate it’s movement with turning left/right.
A thing that annoyed me is when table top games use a non determinist way to define player order. It always depends on the observer.alIf you just say “then the you pass your turn to the left”, what left? From my perspective; from the top down perspective translating it to counterclockwise? From the tables perspective which is the opposite?
I remember when my grandpa was like why not just keep going? I was pulling the ratchet end of the wrench off the bolt at the bottom… I said but that side is left and he laughed and said its just to get you started and told me the clock thing. Dont ever ask me to put a nut on a bolt I will cross thread it every time.
I used to feel the same way. If you’re talking about the direction you’re moving your hand, it assumes your hand is above, not below.
Had a similar hangup with less than/greater than symbols.
The Right Hand Rule (RHR). Point the thumb of your right hand in the direction you want something to go. Curl your fingers. That is the direction of rotation. Translate to any language which has hands.
I guess I’m an idiot because I don’t understand lmao
Your thumb is an arrow pointing at where you want the screw to go. After you curl your fingers, your fingers are arrows showing the direction to turn the screw
I know how to turn a wrench. Knowing the direction is the difficult part. Especially on toilets.
The right oppresses, the left liberates
Lmao
The odd left-threaded screws are called Linksgewinde in German. Knowing this, you can sort of figure the rest out.
Aren’t left handed threads used when there is torque or rotation that would cause nuts on right handed threads to loosen?
Yes. Bicycle pedals for instance.
You can cover right/left with “right is the hand you write with, and left is the one that’s left” and be good for 80%-95% of the population.
In austrian german dialect, “Mit da Ua, draht ma zua.” which in standard german would be “Mit der Uhr, dreht man zu.” and in english “With the clock, turn it closed.” or something like that.
Da scheißt di au!
Neat. Would be engineering related lol
In English, there’s also “clockwise-lockwise”. It makes more sense than talking about left and right.
Probably a result of turning wrenches since I was first able, but that rule, to me, feels akin to “up the stairs take you up, down the stairs take you down”.
The Spanish version is my favourite: la derecha oprime y la izquierda libera (the right oppresses and the left liberates)
Holy shit, fucking hell, now this is some goddamn wordplay!
I’m stealing this like the fucking British Museum.
That’s awesome.
¡Gracias por la lección de español de hoy!
BASED
I think I saw that on reddit 2years ago, thank you for reminding me how’s the actual saying (I ~have adopted ever since I saw it, lol)
Oh wow that one is really good :D
I’m using this in every language I speak from now on!
I had never heard that before. Is that a region or country-specific thing?
Definitely not a common phrase. I’ve never heard of it (from Spain) and I just asked about 10 others from other countries and only one has. We usually would just say clockwise or counterclockwise
Isn’t everything in Spanish?
In Dutch we have DROL, Dicht recht, open links. So close right, open left as a very strict translation. But DROL is also Dutch for turd.
A droll factoid.
Never heard of that, I just remembered from my dad that clockwise is tight and counterclockwise is loose.
Same here, except for my dad, he is clumsy as hell.
Huh, I always say links los, rechts rotsvast
