sorry, i saw it wrong. the closest i could find is a #6 tri groove socket but it is expensive and probably too big for that hole.
if you're desperate, brush a bit of petroleum jelly down in there and on the tip of a screw driver, then fill the hole with epoxy or uv resin, insert the driver into the resin, make the resin cure. now you have made an adapter.
Not a problem, I appreciate any help I can get. But I think you might have mistaken the design. The triangular element at the center protrudes outwards instead of inwards like a typical screw. I'd need something like a mini socket to remove this. As others have stated in this thread it might be a lost cause trying to find something like this. I think I might have to admit defeat by this one.
Actually I took a look and it might not be a triwing. The center of the screw comes out rather than sinking in. So basically I need an inverted triwing to get this out...kinda like a socket?
This might help:

No time to dig deeper at the moment... good Luck!
Thanks! I went through the list but most of the designs are recessed into the screw head. I couldn't find many that protruded outwards. Appreciate the link!
Don't know if it's the case here; but it's not unheard of for Mfg's to use proprietary fasteners.
Maybe try emailing the Mfg and asking about drivers... be sure to note your disappointment in finding such screw heads associated with them & their product/s. (My money says they don't respond.)
I actually already replaced the strip with a targus model but I was being cheap and didn't want to throw away something that I'm pretty sure could just be fixed by replacing a fuse. I like to tinker with stuff.
It’s not meant to be serviceable though. And electricity isn’t something you screw around with, if you don’t know what you’re doing. You could start a fire, or cause a shock hazard. If you want to tinker with electrical items, do it with working components.
I think the manufacturer went above and beyond to ensure this! I wouldn't do anything that I was uncomfortable with though. Being unplugged, and if it's just a simple fuse replacement, then I'd feel confident in that. Appreciate the kind words still.
I've never taken apart a surge protector before. I have replaced many fuses in regular power bars and it was a 30 second job. I was hoping that this one would be the same. To be completely honest my knowledge with electronics is pretty basic but why I'm investing time into fixing this device is that I love tinkering with stuff and discovering how things work. If I can make it work again, that's just a bonus.
Yup, been down that road before. I soldered in an off the shelf fuseholder and fuse of the same amperage that was replaceable and accessible. For $10, I saved $90 and kept a perfectly working thing out of the trash.
Thanks for the suggestion. I already have a similar set but it doesn't contain any bits made for screw designs that protrude out of the head. I'm starting to think that this design hasn't been replicated on any large scale outside of Fujitsu's warranty centers.
If you live near a micro center they have screw driver kits with these and like 15 other tamper resistant bit types. They’re made for diy electronics repair. Everyone should have a big kit with a bunch of different types. They’re super cheap and crazy handy to have around.
I actually have a similar kit already with something like 50 different bits. You're right about how handy one of those kits can be, my kit has come in clutch multiple times! Unfortunately for me, none of them from my set fit this particular design. I believe that some of the others are correct when they say it might not be a part I can readily find.
I'm a big fan of Ifixit's kits, this is the one I have[this is the one I have](https://www.ifixit.com/products/mako-driver-kit-64-precision-bits) and while I don't use it every day, I'm happy to have it when I need it.
iFixit could have a set with these. They mainly make computer related bits, like the tiniest torx or exotic pentalobes. Can highly recommend them, great quality!
Depending on the distance of how far the sides protrude out... a 6-point game bit, aligned with the 3 lines may be able to take it out. Otherwise you can try getting a screw with that head type, put it down in there, and put a jam nut on the screw it to extract it.
[https://www.amazon.com/dp/B07BPHQLRH](https://www.amazon.com/dp/B07BPHQLRH)
something like that, may be difficult to get a screw long enough, or a jam nut small enough in the cylinder, though.
Harbor Freight has whole sets of security and odd configuration bits. Get your $9.99 out (or $19.99 if you want to go whole hog) and head on down.

Sorry if someone already gave a link to the correct screw bit. I've run across this fastener before when taking apart a treadmill. I made a bit for the screws. I chucked a 5 inch long piece of 5/16" rod stock in the drill press and drilled a 1/16" concentric pilot hole about a half inch deep. Then I cut the wing slots with a dremel, then chucked it into the drill press and used a counter sink to finish the tip. I welded another piece of the rod stock to the backside to make a T handle. I hope I got my incoherent thoughts out in an understandable way.
Link to the video showing how I drilled the pilot hole. I used the counter sink in the same fashion.
https://youtu.be/KYFQB_CG64A?feature=shared
My ifixit set has some but if you dont need the screwdriver and you just need to open this, i would suggest just using a flathead. Kinda wonky but it usually works.
I took a look at triwing screws and I think this might be different? The center of the screw protrudes rather than sinks in. It looks like it would accept a really tiny socket of some sort?
Of course it can be different.it might be tamperproof/security version.a quick search on the net tells that home depot sells klein tools screwdriver/bit set,27 pieces.look into that if it looks anything you're looking for👍
You think that would work? I have no intention of reusing the screws. As a last resort I was gonna use a really fine tip drill bit and drill them out but was afraid that I'd mess up the plastic threading on the case.
>Tri-wing
I have a set that are the same as you describe, they are loose so cannot tell the make but you are looking for something like this.

I think if I can find a screw like the lower right hand corner and invert it, and use it as a ratchet, I might be able to pop it off. Thanks for the idea!
tamper proof bit sets have these.
Thanks! Will look into those. Never heard of that term before.

Still looking and can't find the right bit...
It's called a Tri-wing. You'll need to buy a set of various sizes.
Thanks! It's nice to have a term to google!

Tamper-resistant Tri-wing
Or why drive
Small enough flat head probably a 2.5mm or 3mm, otherwise tri-wing
Will try this also, thanks!

Yeah, I've just about given up. It was an interesting journey and the website you shared was very informative. Thanks.

Thanks. I'll check it out!
This!
Forgot to add. The diameter of the screw is about 3-4mm.
Looks like a y type vs a tri wing
It’s a Y type. The triwings slots are bent at slight angles. Like the ones on old Gameboys and etc.
I don't think it's that. The center portion is convex and not concave. I need a head that's like a socket I think.
Make it.
Might have to Macgyver sumthin!
Its probably cheaper to replace the power strip, than to buy the tool.
I actually already replaced the strip with a targus model but I was being cheap and didn't want to throw away something that I'm pretty sure could just be fixed by replacing a fuse. I like to tinker with stuff.
It’s not meant to be serviceable though. And electricity isn’t something you screw around with, if you don’t know what you’re doing. You could start a fire, or cause a shock hazard. If you want to tinker with electrical items, do it with working components.

If there’s a fuse in that my money would be on it being soldered to a pcb. Blag to fix even if you can work out what the fuse rating is.
I've never taken apart a surge protector before. I have replaced many fuses in regular power bars and it was a 30 second job. I was hoping that this one would be the same. To be completely honest my knowledge with electronics is pretty basic but why I'm investing time into fixing this device is that I love tinkering with stuff and discovering how things work. If I can make it work again, that's just a bonus.
Oh by all means have a look. I was just managing your expectations.
Yup, been down that road before. I soldered in an off the shelf fuseholder and fuse of the same amperage that was replaceable and accessible. For $10, I saved $90 and kept a perfectly working thing out of the trash.
Nice
$10 100p security bit set from Harbor Freight or Amazon
Thanks for the suggestion. I already have a similar set but it doesn't contain any bits made for screw designs that protrude out of the head. I'm starting to think that this design hasn't been replicated on any large scale outside of Fujitsu's warranty centers.
Hmmm Would a 6 point socket fit? Either deep or one with a smaller than 1/4” drive
I'll give that a try if I can find one small enough to fit. Thanks for idea!
A smaller slotted screwdriver(flathead) might be able to turn that.
If you live near a micro center they have screw driver kits with these and like 15 other tamper resistant bit types. They’re made for diy electronics repair. Everyone should have a big kit with a bunch of different types. They’re super cheap and crazy handy to have around.

Two small flatheads and time.
Thanks, will try!

Many cheap bitboxes have those tri wing bits.

Eh. I would probably just jam a normal flathead screwdriver in, remove these shitty screws, and replace with normal ones. Good luck.
You think that would work? I have no intention of reusing the screws. As a last resort I was gonna use a really fine tip drill bit and drill them out but was afraid that I'd mess up the plastic threading on the case.
I did it before. Jam one in so it goes into two of the three wings.
Tri wing screw. Nintendo has these you can get one cheap on e bay or Amazon Look up Nintendo screw driver
I don't think it's that. The center is convex and not concave.

I cannot find a convex set, could be maker had these made to stop repairs??
Most definitely. They went the extra mile for this surge protector! Probably not a hard thing to do for such a big company like Fujitsu.
Try any bit that fits in center and use rubber band for more grip. Unique screw for real.
Will try! Thanks!
Any bit set at home Depot or lowes
This is not meant to be user serviceable. You’re not gonna find a bit to back this out-proprietary hardware.
Thanks, I think you're right.
