triggertreatThings with reverse threads..
On high speed centrifuges it was lefty tighty on the internal bowl parts and righty tighty on the external module parts. Muscle memory made it easy but it was a bitch working normal things off work.

Jeff YarchinOur Motorhome wheels have reverse threads…22.5 inch Alcoa wheels. Good idea to remind the techs when it’s time for new shoes.

On my Hustler zero-turn it is the opposite. I hit a tree root and spun the blade off. I'm guessing it is set up this way to prevent damage in such a situation.

sig operatorSome drill chucks where screws in the center hold them on.
Gas cylinder threads - usually have the corners of the nut cut to denote reverse thread.

architectThe Lounge occasionally has reverse threads, e.g. "What's the worst thing that ever happened to you?" vs. "What's the best thing that's ever happened to you?" Like threads on machinery, people sometimes turn these the wrong way.

I was going mention purifier retaining rings...kind of a specialized field.

darthfusterMy USP Tactical has left hand threads. The Mark 23 has right hand threads. I believe this was designed to make me buy two Knights suppressors.

Hamden106Left threads, right threads. And centrist threads. I have here in my hand a "screw" with threads neither left or right. The thread cuts are rings with no left or right pitch.

Yes it is. Do you work in the field?

That's extremely interesting. Makes sense for expensive commercial mowers like that. A lot when you think about it. Hitting a stump on a home grade mower is one thing, doing that with a commercial prob a different ball game.
