    I hate righty-tighty lefty-loosy. Depending on whether you’re looking at the top or bottom of the screw, you can see movement to the right or the left. I hate whoever came up with it, and I wish I had been taught the right hand method. It works exactly the same as the electromagnetic right hand rule:
    an example of the right hand rule as it relates to a screw thread

    Basically, you take your right hand, stick your thumb out, and curl your fingers like you’re grabbing a broom handle. Point your thumb in the direction you want the screw to move to. Want to screw something in? Point your thumb towards the thing. Want to unscrew? Point your thumb away from the object the screw is currently in. Then, just look at the way your fingers are pointing! If it helps, squeeze your fingers into a fist and see which way they move. Alternatively, bend your wrist in, and observe which way your fingers are moving. Works every time.

    It sounds complicated, but there are plenty of people who are unable to intuitively differentiate from right and left the way they can differentiate up and down. I am one of those people. Thanks to this method, I’ve been able to develop the muscle memory/intuition to know which way to turn a screw.

    It’s important to note that this only works for screws that are “right hand threaded.” If the screw is only getting tighter when you’re using this method, then it’s likely reverse threaded, or left hand threaded. If that’s the case, just use your left hand instead of your right hand.

      … Neat.

      Alas, most people know which way is left or right. In reality it’s more clockwise vs counterclockwise. A good friend of mine needed that hold their left hand up and make an L to remember. Doing it with your right makes a J. Unless you somehow associate Left with Jeft in which case you probably pronounce gif wrong too.

      Whichever works for you is great. It doesn’t mean mean everyone is ND or has a learning disability.

    If too much righty tighty then it might become loosy

      “little bolt no good anymore” - maybe don’t use caveman strength on an 8mm bolt that holds no weight???

        Seen it too many times. The biggest guy on the team grabs the biggest wrench he can find for the smallest fastener on the assembly. Maybe the wrench bends, maybe the head snaps, I’ve seriously considered getting torque limited Allan wrenches.

          I recently had someone complain about a bolt getting hot while they were wrenching it. they created enough friction to notice it heating up. and then kept wrenching it.

          also, I’ve started replacing normal bolts with rounded hand-bolts, which are nearly impossible to over-torque, so long as they don’t take a pair of pliers to them.

    I’m not sure if it’s a symptom of a mental disorder but I struggle with right vs left to this day. If someone says “turn left” it takes some mental power for me to decipher. But clockwise / anticlockwise is easy for some reason

        This. I have mild dyslexia and dysgraphia and I refuse to give driving directions. I will point left, say right, and not even realize it and just confuse the shit out of my driver, lol.

        Hell, I refuse to accept directions. My navigator will say left, I’ll go right, and they’ll look at me funny. If we’re in my car, we’re using GPS. No exceptions, even if we’re just going 3 blocks.

        • I’ve found that Driver’s Side/ Passenger’s Side works for me, though I’ve never been to somewhere that drives on the driver’s side of the road, so that could trip me up.

    I learned it the other way: Lefty Loosy, Righty Tighty. Your version sounds so wrong to me, but I presume mine sounds wrong to you wrong people.

    Not on all vehicles.

    I broke 2 lug nuts off a Willys Army Jeep I was restoring in High School before I figured that one out.

    just watched a sadly hilarious video of a mechanic struggle with reverse threads on highly specific rotating assembly. like, I get it, it’s not immediately obvious, but edit that wrong turn out if you want to make a serious explainer series. also, if you work with pivots that often, you have to expect that shit.
