Impossible double threaded bolt.

  • Published on Apr 4, 2021
  • I found this double threaded bolt a couple of months ago on TheXvid. It was made of metal. About a week ago I had an idea to print the double threaded bolt on my 3d printer. Not is is my favorite toy until I print something else. :)
    My printer - Ender 3 v2 -
    Filament -
    Original bolt video -
    3d printed two way screw -

      @HisMajesty It is called filament, not an ink. And price varies on the amount you want to buy.

    Yep, can confirm its possible... can also confirm there is a very good reason they don't make bolts like this.

      @Saturn Media exactly as a machinist I was going to say the same thing. The thread walls are where all the pressure is held and on a 6 lead multinational thread all the wall is cut out except for those diamonds which is exponentially weaker. The machinery handbook is loaded with so much information that most people couldn’t begin to understand, hell I don’t understand a lot of it myself and have had to use it for threads for years lmao

      I always hate when I ask “which way” and someone says this. Do you not see how either way you turn something it can appear to move left or right. Clockwise and counterclockwise are much easier terms as well.

    This is why nuts and bolts have spiral threads. Otherwise you'd be driving down the road while your car slowly disassembles itself. Lol

      @Andy Spivey The fact that you even made this statement is enough evidence to conclude that you are not a better owner of that vehicle as the previous owner. So it is safe to say that it must be a decent vehicle if it has survived lack of care and love.
      I at least hope the car is clean enough, if not it could self ignite and start burning.

      It is not even my project, I just 3d printed it because it looks unusual and cool

  • I only make playlists now :(

    The reason this works is because it has the indents from both bolts but still has structure so it isn't just a not pointy nail

  • the.beard.yyc

    So it basically can’t torque onto any that could ever shake or move or be touched, sounds… cool?

  • kelly hill
    kelly hill 9 months ago

    Getting a nut to thread both ways such as this isnt the hard part. But your forgetting the purpose of the nut is to TIGHTEN DOWN that will not happen with any of the nuts shown. Too much thread play is needed for them to tighten down to any degree

      Because it cant torque onto anything. If it unscrews the same way it threads on; it will always be loose.

  • Natpk
    Natpk 7 months ago

    I know it's a puzzle, but if you really wanted to use this on most situations... it wouldn't be useful, because for example, take the red thingy, you can unscrew it from both sides, losing the point of a screw, wich is meant to hold things

      It wont torque onto anything so it will always be loose because it comes loose the same way it becomes tight so it is a matter of shaking for it to wiggle off.

  • Dragonfire1954
    Dragonfire1954 7 months ago

    That's not really hard to find the reasoning, the green ones are clockwise and counter clockwise respectively, and the red one is straight, so when you twist the red one it will move in any direction you push it.

      Most likely the red one isn't actually turning in relation to the bolt; you could probably just push it on. Maybe that's true for one of, if not both of the other ones.
