Basic blender went bad (motor ran but spindle wasn’t rotating). I wanted to disassemble to see if it could be repaired. Three of the four screws were Phillips head. I had to cut the casing open in order to discover why I couldn’t unscrew the fourth. It was a slotted spanner.

    hahahahahaha, about three years ago now, I bought a hunting knife from Amazon that came with a sheath which had a belt clip that was held on by one of these fucking screws.

    at the time, i couldn’t figure for the life of me what it was or if there was a tool for this so I went to Home Depot, bought a .99 cent flathead our of their bargain tubs, took it to their tool rental department where they also will cut metal for you if you ask nicely. had them make a notch in the top of the flathead, brought it home and after some filing got it to get in there and loosen up this devil screw top.

    now i know it’s called a U or H type screwdriver. my way was cheaper, but nice to know the real solution now.

      That belt clip is there to make the knife technically legal in some areas. A 3"+ blade can’t be concealed by putting it in your pocket, so the workaround is to have the clip showing on the outside of your pocket, making it visible. That’s why they use screws like that. At least that is my understanding - I could be wrong.

    Just a basic security screw. It’s so kids (and people who don’t know enough about repairing appliances to know about security screws) don’t disassemble the dangerous machine.

      Though it should be noted this does raise the bar above most people, especially on a budget, single use tools are hardly ever worth it.

      Arguably more dangerous things have easier screws too, like electricity outlets

        Grinding a notch into a flathead screwdriver is annoying but it’ll still work fine as a flathead even afterwards. I would probably just grind the bulge out of the screw though.

          I have a set of these that was part of a larger set of precision bits I was buying anyway. I’ve only ever used one of the security bits in like a decade of having them. I wouldn’t have bought the security bits alone.

      This right here. I bought their security bit set and, true, I’ve only ever opened the case three times in the few years I’ve had it, but in those three times nothing else would have worked without a more destructive solution

        Here’s the link, it’s helped me out a bunch of times in the 6-8 years I’ve had it.

        2 notes though

        • these are hard cheese grade metal. Don’t plan on removing any high torque, Rusty or partly stripped screws with them, they’ll either break or round off.
        • if the screw is too recesses down a narrow hole, these won’t help. The bit holders are too wide to fit in. I have a Honeywell Air Purifier with one security Torx that is 3-4” down a hole that this set failed me on.

          Just to add to your comment, the sell a smaller set for a few dollars less and also a “precision” screwdriver set that has some similar bits not but the full set. Both are very handy to keep around for this exact thing.

    It’s called an “H-type” head. I found some tools for that on eBay but was reluctant to spend any money on something I’d probably never need again, ever. But this video shows a hack using scissors.

    https://www.youtube.com/watch?v=GA6_S9YkZEc

    I didn’t have a pair laying around that worked but the video inspired me to MacGyver my way to remove that aberration against all that’s good in humanity.

    Buy a security bitset! It is surprisingly handly to have around. Sometimes, I’ve needed a certain screw size that they don’t have in imperial, but they do have in metric at the hardware store. But it’s a security bit only.

    They also work on regular, non security bits in a pinch.

    A grinder to the center would make that compatible with a flathead screwdriver.

      I think this was at the bottom of a deep hole, as you can see where the plastic was cut around it. A standard bit and holder wouldn’t fit down that, I don’t think. What the other guys said about a flathead and dremel/grinding wheel is the only option really, but you’d have to be able to ID the little fucker first.

    If you haven’t already, look into getting a ratcheting screwdriver with replaceable bits, and a pack of various bits for it. Idk where I got it, but I’ve got all kinds of screwy bits (including the H-bit head) that I need very infrequently, but I’m always happy when I do and I already have it.

    I think the bit pack I got was for the security torx and it came with a bunch of other stuff.

    If you have a Dremel, I bet you could take out the center bit and use a regular slotted screwdriver.

      $10 says it was recessed before op cut the base off, making it impossible without damage to slot the screw with a Dremel.

          Damn, I didn’t even think of that. It would be ruining a good screwdriver, but you could just use an old worn flat-head drill bit.

          Good call, either way.

        Take a flat screwdriver and moubt it on a vice. Take your angle grinder, mount a disk for metal grinding. Grind away the middle of the flat screwdriver head. Done it before for the exact same purpose.

    My vacuum cleaner. You know how the roller brush gets all tangled up with hair and threads and whatnot, and the way you fix that is to remove the roller and cut it all out?

    The external screws are torx security bits. The internal screws are Phillips. The only reason is to get someone who isn’t persistent to go buy a new vacuum cleaner when their roller gets tangled

    • I just pull the hair directly off the roller as is. No need to take it out. I clean it often enough that it would take more time to take it off no matter what screws it has. The worst part imo is the internal screws being phillips. Torx (whether “security” versions or not) > Phillips/Flathead.

      At this point I think at least a modest tamper kit should be in a household the same way a screwdriver was previously.
