Screws are one of the marvels of physics. The threads can exert huge amounts of force, with far less input than you might think, and this means they can be used to do all kinds of things. In this particular case they are being used as a press so that Jason at Fireball Tools can measure the force they are able to exert. And that force is considerable. But how considerable, and is there a major difference in the amount of force they can exert based on diameter? Is the larger screw capable of more or less? Watch and learn.

What screw is more powerful? A large diameter or a small diameter? I test the force of 4 different screws diameter. Let’s find out. I’m working on a cool project, but need to find the best screw for the job. Today I test many screws, all with the same threads per inch, in order to determine the ideal mechanical advantage to friction ratio.
