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........

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 🫑

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

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

I heard from a gas guy that this is to ensure that only connectors made for gas usage are used and people don't build crazy contraptions with plumber gear for flammable gases.... Kinda makes sense.

Yep, 80% of the time it works every time!

The point is, if you fix things, you WILL run into left handed threads at some point. I've found them in washers, vacuums, blenders, bikes, and cars. Left handed threads aren't the most common thing, but they are out there waiting to screw with your mind and ruin your day.......
