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?

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 have left-hand threaded fittings on a few things and always say to myself aloud "This is reverse-threaded" before I attempt to turn them then still fuck up first turn. It doesn't stop me from fucking it up the first time - it just helps me remember why.

When I train new people on this equipment I tell them to say it aloud, show them, still fuck up the first turn, then they laugh.

Then I have them do it in front of me including saying it aloud - and they fuck up the first turn...

When you've been doing something unconsciously for decades it's really hard to break.

I think it was old Chryslers had opposite lugnuts, I can only imagine how many stripped threads happened
