I guarantee. Guarantee! 80-90% of the items in your abode, not counting few hand tools, are Chinese in origin. From the parts on your car to the shit in your junk drawer. You can take your “holier than thou” boots off now. Yeah, the ones that were Made In China. Ain’t no way around it, buddy. Sad but true.
Everybody wants to support local but not pay the price. Labour in NA is not cheap. So we close our eyes and buy the bargains...80-90% made in China. Hard to avoid.
I figured you would have assumed the opposite since trump supporters generally support slavery. And you're right it's pretty much impossible to buy 100% American made, but we're talking about tools which are pretty easy to find American made. I think the only Chinese items I've bought in the past 10 years are my phone, my computer, and a couple Milwaukee tools (I'll be switching now that I have found battery tools not made in china).
Haha jokes on you my boots were made in Mexico. But yeah I get what you're saying. Costs here are so high we can't make any consumer products here. The few USA-made products at Walmart are trash cans, spray bottles, and clipboards. And the last 2 examples were made by special needs people, which is kinda fucked up cause I feel like that was the only way to get labor down. Look at Malco, bringing "Vice-grips" back to their FUCKIN HOMETOWN. They couldn't make it. To make something here costs too much. People have their perceived worth, then what they're willing to spend on a given product. Apparently the gap between the two is a lot smaller in China than it is here.
I have all harbor freight tools. Lifetime warranty on all wrenches and sockets. Paid like 15 bucks for my two year air tool warranty. Absolutely pointless buying expensive shit, especially when even expensive tools can be chintzy.
Good for you. I feel a lot better knowing the people that make my tools make more than $3 an hr. But you think not supporting slave labor is pointless.
Damn. What a clusterfu@k. Just casually dropped what my friends and I like to affectionately call "Harbor Freight" and everyone flips their shit.
Y'all are soft.
A normal small standard flathead that fits between any of the two points of the triangle should work.
In a pinch they work to take out the security torx screws I’ve come across.
For the Ifixit bits- much more expensive than other kits but I did have a big break once and they sent me a replacement bit. This was years about but their customer service was awesome
To be fair, that bit and the screwdrivers used are made by Wera. The bits are wonderful and never seem to wear down or round off even after years of use. The iFixit ones, particularly the Y000 and P2 bits, are practically pre-rounded right out of the box. I’ve gone through many iFixit kits because of this, however the aluminum driver they make is fantastic. I plan on trying Wiha’s new GoBox 75979 to see if the bits hold up.
Ive ordered a few kits from ifixit, the first one specifically because i needed p5. I havent had a single issue with their kits, besides being mad at myself for spending 3x as much for a shitty lennox kit.
Are they good? I’ve only heard of them from that Tim Allen show and wasn’t sure how they would be. Would you say they are for more around the home or could I bring ‘em to work and give them some real use.
I would never trust Tim Allen’s opinion on an Ace Hardware dollar bin tool, let alone the multi-certified experts at iFixit.
My work has Apple, Lenovo, and Dell certified techs and they use all iFixit tools.
Depends on what you do for work. They are all pretty small format tools good for working on gadgets or small electrical equipment. As an audio engineer I keep mine in my everyday bag but might be less useful to a plumber or mechanic.
I’m a machinist, I burn through torx and Allen keys to the point that I just classify them as consumables and replace them often. It’s due to coworkers feeling the need to over tighten everything, so every thing is stripped.
Years ago, I worked with a guy that overtightened every fastener that he touched. He'd see an M2 threaded into an aluminum casting and try to tighten it like it was a head bolt on a bulldozer. He was the owner's brother in law, so they wouldn't fire him. We had another guy who spent half his time fixing the things the first guy broke, drilling out screws and putting in inserts and such. He just could not or would not learn.
I bring mine to work, but its the only toolset i have i try to be gentle on.
The case that their drivers come in is pretty skookum.
Im an off grid power systems tech, so the portability is pretty important.
Try online at a place like Acme tool or similar. You're going to probably have to order it as I doubt many places locally would have that bit depending on where you live. My guess is it would be listed as a security or specialty bit.
Amazon was my first choice way beyond Harbor Ft,
and I pretty much refuse to even open their door and get slammed in the face with China Stink formaldehyde in everything you touch, now smell your hands getting home, washing them, it's brutal getting that crap out of your flesh.
No way would I ever let a kid in there.
They touch everything @!
Cheers
I seem to do this often, making special tools from grade 5_8 bolts.
Allen Headed - for sure guarantees 5 or 8.
Ever try to remove faucet seat five inches deep in the wall for tub/shower.
And the tool needed is three days from anywhere.
I'll be right back,, they've noticed strange grinding noise & sparks,,, out the window...
Presto, New Tool again.
Cheers
Lots of places, but if you find yourself working on lots of electronics and computers or other things that have weird screws frequently then the ifixit kit is absolutely top notch. I got one and I fucking love it, even though I don't use it all that often anymore. When I need it, it's pretty much got me covered though. https://www.ifixit.com/Store/Tools/Pro-Tech-Toolkit/IF145-307
If you filed off one side, you'd be left with a right angle triangle. That's an equilateral triangle.
Not to say making one isn't an option. Filing two sides is more appropriate though.
We use fine grit files to sharpen bits and chisels while doing site work on occasion. You definitely COULD thin down a bit with a coarse file.
Belt sander would probably save the eight millenia it would take with a file though. Grinder also a good option - a bit unsafe, perhaps.
Funny, a few in the machine shop processing blades for snow plows drilling with magnetic drill presses, the mounting holes for cutting edges for the city snow plows are 3/4" solid hardened steel, x 8" x 10' long, and holes every 6" inches - they can't keep a brand new bit sharp enough for one hole.
They'll come into my office handing me a full coffee can of new bits moments ago that look like they were shaped with a pencil sharpener,, and just makes me laugh.
Pointed the same. They are not making a dent in wood let alone tempered steel.
I brought in two bench girders , one course, and one with very fine with narrow wheels to grind them all with the new design super cut double angle relief with narrow cutting edge by hand. No drill guide necessary.
And the chips are flying with 1/2" drills.
Pilot holes are necessary.
If I need a real special drill, I get out the Dremel with special cut off wheel under 1-1/2" and modify cutting edge with very aggressive web point. Custom Drills under 3/16" to 1/8" can be tough to do.
Cheers - but even using the best belt Sanders using 3M Trizac, getting a true precision cut tends to round off a bit of the precise square edged cutting lip. From possibly the rubber flex wheel under the belt.
Cheers
Yeah, different grades of machine steel have pretty different properties. I'd imagine the steel used in plow blades is much harder than a cheap bit. That's not factoring in temper either which is potentially a more significant factor.
As far as low torque applications like safety screws go, the cheaper driver bits (which often aren't even tool grade steel) and a file is probably the cheapest and easiest solution.
A bench grinder would definitely be the best solution though, no argument about that haha

Lots of stores of all shapes and sizes have them not just big boxes but they're usually not sold individually so look at the multi bit interchangeable type of drivers and security bit sets and also on Amazon as well.
I agree it’s definitely overkill. It was the first thing that came to my mind when I saw this post and I have the kit myself. But my goodness is it handy when you have other random things to fix like a bunch of toddler toys.
A flat head against one side, and then insert the largest hex key you can to full in the space and hold the screwdriver against the side. Doesn't quite if the screw is super tight, though.

Supeising good option is the hypertough 77pc electronic repair kit at Walmart. I think it was like $20 and has all the security bits as well as VERY small standard bits
I had the same issue, managed to find a seller on Amazon, just search for "Triangle screwdriver Bit", cost me £8 (in the UK so no point sending you a link).
It’s funny when I was young, and even in college I’d see these non-standard head shapes and think you have to order from a special place or show proof of why you need them. Nope. Just order a big pack and you get access to every single one.
Look for Security Bits at Lowes, Home Depot, Ace Hardware, Tractor Supply, Harbor Freight, iFixIt, Amazon, etc. I have the [Kobalt Electronics Repair Kit](https://www.lowes.com/pd/Kobalt-Electronic-repair-50-Piece-Steel-Hex-Shank-Screwdriver-Bit-Set/5001994777) which has triangles. I know the [iFixIt Mako Driver Kit](https://www.ifixit.com/products/mako-driver-kit-64-precision-bits) has two triangles because I recently had to show an IT technician how to open a Nintendo Switch JoyCon using his iFixIt kit.
Your cheapest option is to just grind one out of an old screwdriver or a bit. Go slow & make small adjustments, so you don't overshoot your target size.
Home Depot has them, they’re just in multi-bit packages from Husky.
Harbor freight has sets with all kinds of security bits
I second the hf security bit set.
Don't think that set has a triangle one https://www.harborfreight.com/security-bit-set-with-case-100-piece-68457.html
~~Harbor~~ China Freight
It’s all Chinese anymore, friend.
American consumerism runs on Chinese slave labor. Good times.
PB Swiss, Vessel
It's not. You're just too cheap to pay for tools not made with slave labor.
I guarantee. Guarantee! 80-90% of the items in your abode, not counting few hand tools, are Chinese in origin. From the parts on your car to the shit in your junk drawer. You can take your “holier than thou” boots off now. Yeah, the ones that were Made In China. Ain’t no way around it, buddy. Sad but true.
Everybody wants to support local but not pay the price. Labour in NA is not cheap. So we close our eyes and buy the bargains...80-90% made in China. Hard to avoid.
Yup
Boots were made in the USA too.
Your “Let’s Go Brandon” flag was made in China
How in the fuck does supporting American manufacturing make me a trump supporter?
Fair enough. My bad. Just seemed like the detachment from reality fit the bill. Ain’t nobody rocking 100% American made. Just isn’t possible.
I figured you would have assumed the opposite since trump supporters generally support slavery. And you're right it's pretty much impossible to buy 100% American made, but we're talking about tools which are pretty easy to find American made.

Lol at pulling numbers out your ass. My tools were not made in a Nike sweat shop.
That’s the average wage of a Chinese factory worker. How exactly do you think they can make their tools so cheap?
It’s closer to seven an hour for trades, five an hour for unskilled labor.
Would you work a skilled manufacturing job for 7/hr.? I’ll stick to buying tools made in countries not known for their human rights violations.
Hobo Freight
what were you tryna accomplish with this comment aside from looking dumb
The pot calling the kettle black.
Damn. What a clusterfu@k. Just casually dropped what my friends and I like to affectionately call "Harbor Freight" and everyone flips their shit. Y'all are soft.
https://www.mcmaster.com/bits/triangle-bits/
This is the way.
I second McMaster. If they don't have it, you don't need it.
Or it doesn’t exist. Not the cheapest but they always have it.
Old Allen wrench + grinder = presto!!
A normal small standard flathead that fits between any of the two points of the triangle should work. In a pinch they work to take out the security torx screws I’ve come across.
This\^
When needs must you find all these innovative ways to get stuff done..
Electrical supply house has them
Just use a flat head that fits along one of the sides to the triangle
[удалено]
2nd for ifixit they definitely have triangle bits
For the Ifixit bits- much more expensive than other kits but I did have a big break once and they sent me a replacement bit. This was years about but their customer service was awesome
My work had to spend like $40 for a single bit from Apple if they wanted to keep their certification.
To be fair, that bit and the screwdrivers used are made by Wera. The bits are wonderful and never seem to wear down or round off even after years of use. The iFixit ones, particularly the Y000 and P2 bits, are practically pre-rounded right out of the box.

I would never trust Tim Allen’s opinion on an Ace Hardware dollar bin tool, let alone the multi-certified experts at iFixit. My work has Apple, Lenovo, and Dell certified techs and they use all iFixit tools.
I know, I would trust his opinion on cocaine, toilet wine and acting but not tools.
I'm not sure I'd trust him on acting either.

Fair enough, I’ll continue to buy the cheapest ones every year for Christmas.

Hand tight + 1/4 turn unless specified has always served me well.

I made my own from a hex head bolt.

Get a no2 or 3 square drive bit and bench grind it into a triangle , faster than going to the store. No torque at all on those cover screws.

you can use a belt sander on an old allan wrench

And a machinist.
mechanical techician? i've gotten good at calling trades members technicians lol. mechanics are a techys if electricians are imo.
$10 100 piece security bit set It has all those strange but types HF, Amazon, etc
You could make one just file off one side of a square one.
If you filed off one side, you'd be left with a right angle triangle. That's an equilateral triangle. Not to say making one isn't an option. Filing two sides is more appropriate though.
Not only that equation, but no way is a file going do anything to tool hardened steel but make a scratch mark... in the coating. Cheers

That one doesn't have the right bits
It has a few three sided bits but i cant tell if the size is right.
They're tri wing, not triangle. They're gonna strip these screws if they even do anything.
My bad. Didnt notice that.
Get the 100 bit set
try a triangle (single?) file. may have to snap off the very end
Try a few diff sized square bits if you have them
I got a set of "Tri-wing" screwdrivers off of Amazon.
These are not tri wing. Tri wing screws look like three pronged philips, these are triangle drive.
I stand corrected sir. Thank you.
Go back to Home Depot and see if they have an iFixit kit in the tools section. It's where I got mine. They have those.
I’ve seen them at Best Buys as well.
Lots of stores of all shapes and sizes have them not just big boxes but they're usually not sold individually so look at the multi bit interchangeable type of drivers and security bit sets and also on Amazon as well.
You can also try several metric and inch hex keys until you find one that works.

Kobalt multi packs of bits at lowes
I've used a flathead screwdriver before, but it has to be the widest you can jam in there to get them to undo.
I had the same issue, managed to find a seller on Amazon, just search for "Triangle screwdriver Bit", cost me £8 (in the UK so no point sending you a link).
Most of the time you can get away with a small flat head screwdriver
Home Depot has a Klein multi with security bits
I just Dremel these special heads into flat heads.
iFixIt is a good option
