    I see, you decided to pick 2 pieces of shit.

    Phillips proceeds to strip when I look at it badly.
    Slotted keeps kicking out the screwdriver.

    Robertson is the top. It holds onto the screwdriver even without magnet, and good luck stripping a square.

      Philips is designed to allow the screwdriver to slip out so you don’t over-torque the screw. If you’re stripping them, you’re probably using too much torque. But, it might not be your fault, because a lot of people use Philips screws when they shouldn’t, and use too much torque when screwing them in.

      As for slotted, those just suck. I guess one benefit is that you can use an over-sized head on small screws. But, slotted is really the wrong choice almost every time.

        Philips is designed to allow the screwdriver to slip out

        That’s a myth. I’ve read the entire patent and there is no mention of it, and later patents are just post-hoc justifications for an objectively faulty, inferior design.

        My charitable hypothesis is that the design uses shallower angles that are easier to cam out because sharp angles would result in stress fractures during the cold forming of the screw heads. My realistic hypothesis is that dies with shallow angles are cheaper to produce and more durable. But the point is moot: the Phillips didn’t become the de facto standard because of any practical advantage (real or perceived), but because Robertson wasn’t willing to sell exclusive rights to Ford.

        I’m usually not one to criticise a person’s life choices, but if you think Phillips is better than the popular alternatives, I immediately think less of you as a person.

      Phillips usually strip when using a pozidrive screw driver on them. Very common mistake because people think they are the sams, but easy to avoid once you know it.

      Also, the fit has to be tight. If it’s loose, the screw driver is too small.

        Posidrive is not that common and not the problem. Phillips heads strip because they’re designed to cam out and prevent snapping heads or overtorquing. JIS is same cross shape but doesnt cam out, which is good for avoiding stripping the heads but makes it easier to snap the head off of screws

          Pozidrive is very common here in Germany in the form of “Spax” screws. They are the main screws we get for everything from wood working to wall mounts for pictures. They also don’t strip.

          And trust me, I have seen plenty of philips screws beeing stripped ue to the use of pozi screw drivers while beeing perfectly okay when beeing removed with a philips screwdriver. Of course there are toher reasons they strip as you mentioned, but here in Germany its a hige problem because Pozidrive is so common and people dont know the difference.

        Pozidriv drivers actually work very well on Philips screws, sometimes better than Philips drivers, due to the fact that the “vanes” are angled rather than curved, proving a larger contact area. Fit is definitely the larger factor, along with the quality of the screw metal.

        They’re both junk next to Robertson though.
