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.

Yeah we should be shaming companies that do this sort of shit.

OP, please tell us which brand designed this. I’d love to know to stay away from their crap as much as possible.

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.

Wow, doing a MacGuyver with corporate assistance. I like it!

[-] jawa21@lemmy.sdf.org 7 points 1 week ago

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.

[-] Sethayy@sh.itjust.works 36 points 1 week ago

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

[-] nova_ad_vitum@lemmy.ca 10 points 1 week ago

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.

It's a blender... As long as it's unplugged you'll be fine.

Harbor freight has sets of tamper resistant bits. They are also handy for regular Allen and torx heads.

[-] ThrowawaySobriquet@lemmy.world 14 points 1 week ago

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

[-] nilloc@discuss.tchncs.de 5 points 1 week ago

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.

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.


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.

[-] lurch@sh.itjust.works 5 points 1 week ago

in a case i only needed it once, i would solder or power glue something to it to use as a wings handle.

... but that's just me. I'm like eccentric MacGuyver.

[-] Wahots@pawb.social 29 points 1 week ago

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.

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.

[-] NoneYa@lemm.ee 26 points 1 week ago

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

[-] TropicalDingdong@lemmy.world 9 points 1 week ago

Your gonna need a teeny tiny grinder. Maybe a dremmel?

[-] Alteon@lemmy.world 14 points 1 week ago

Everyone should have a Dremel. Damn thing is so useful.

A complete set of security screw bits is ~20 bucks and they're far more useful than I realized until I acquired them.

Grab a dremel tool and make that piece of shit into a flathead

[-] JayDee@lemmy.ml 19 points 1 week ago* (last edited 1 week ago)

That's a flathead with a bead welded in the middle. Source a local dremel, some earplugs and eye pro, and do some quick converting.

Oh wait I think I understand the image. You had to saw the plastic apart to expose the screw. Yeah fuck those dudes. I guess another option would've been to get a cheap screw driver and modify it with a dremel? Either way, fuck Kenmore.

I'd use my dremel to finish the slot that was only partially cut.

[-] chonglibloodsport@lemmy.world 8 points 1 week ago

Or use the dremel to cut a slot in the end of a flat screwdriver.

[-] poopsmith@lemmy.world 17 points 1 week ago

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

[-] ironhydroxide@sh.itjust.works 17 points 1 week ago

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

[-] viking@infosec.pub 10 points 1 week ago

So you use the dremel to cut a groove into your screwdriver instead.

How are you supposed to grind a flat on a screw recessed 2" in a hole?

I didn't even know that that screw type had its own name until I saw it in another comment, but the first thing I thought was to just do what you said.

[-] lightnsfw@reddthat.com 8 points 1 week ago

Cut that middle bit out and make it into a flathead.

[-] an_onanist@lemmy.world 16 points 1 week ago

The screw head was at tho bottom of a 2 inch shaft. I destroyed the casing just to find out what the issue was.

I had drill bits for such screws for decades, never had the reason to use them though. It's nice to see that there's a use for them after all!

The bit set and tool set from IFixIt has those. I'm not sponsored by them in any way, but I will shamelessly recommend their tools when I can because they're objectively good for this kind of stuff.

[-] Nougat@fedia.io 6 points 1 week ago

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

[-] prettybunnys@sh.itjust.works 14 points 1 week ago

Thought they might sell these specialty tools online, but 3 minutes of searching came up with nothing. Might be time to get creative.

Do you have the room to get a Dremel in there the cut it so a regular flathead will work?

If not, maybe try to use needle noise pliers as your screwdriver.

As a last resort, pick up a cheap screwdriver and cut it to make it slotted.

Edit: I love how quickly several people have commented with links to the needed tools. Thanks to all of you!

iFixit sells kits like this that have every screw head imaginable. No need to get creative.

Depending on the size, I've absolutely gotten small versions of these bits in IT/Electronics repair kits.

[-] Madison420@lemmy.world 5 points 1 week ago

I mean a blender isn't exactly the worst things to have security bits on.

[-] an_onanist@lemmy.world 7 points 1 week ago

Really? It seems to me that if you believe blenders should be tamper-proof, you must believe that all appliances should be.
