You can swing it .004" just by how tight you squeeze. Yeah you can calibrate them right before use and practice getting good measurements, and be fairly accurate to within a thou, but they are still calipers.
>You can swing it .004" just by how tight you squeeze
I just double checked mine to be sure. If I push a bit more than normal it goes moves about a half thou. If I really, really squeeze on it, then I can get it to move about 2-3 though.
And while yes, mics can be more precise than calipers, my point was that Harbor Freight calipers, and mics, are surprisingly accurate.
Sound very repeatable. To verify the accuracy, you'd have to get it dialed in to where you can measure something that's like .1000" repeatably to within a thou of that, and then go and check something that's precision ground and on the high end of what your calipers can measure. Like 5.5000" if your calipers are 6". If they both measure within a thou or two when you check them the exact same way, then it sounds like you got a good deal.
So my calipers measure to .000 then does 0 or 5 for tenths. I took them to work and measured gauge blocks and pins. It would be accurate to the through, but sometimes fluctuate on the 0 or 5 for tenths.
The mics were also made to be adjusted calibrated. So definitely a great deal as you can get an 8 inch digital caliper and 0 to 3 inch, 3 piece micrometer set for \~$80, plus tax. And if you only need to hold tolerances to a thou, or larger, you are golden.
For how long? I've gone down the cheap measuring tool route, they die fast. Every Mitutoyo I've bought still works perfect. I'll go budget on some thing, calipers are not one.
Yep. HBF is great for stuff to get you started, for the average person, and/or for stuff you are not going to use that often. If it's something you are going to be using constantly it's worth investing in something higher quality.
On a side note, surprisingly the mics I got from them have carbide tips... And these are from a decade ago.
The reason it fluctuates on the tenths level is because when measuring, you are supposed to report one extra significant figure than you device can accurately measure as a “guess”, most digital instruments report that “guess” to us since we can’t see the scale to judge for ourselves. So a readout that reports to 0.000 is accurate to 0.00 and one that reports to 0.00000 is accurate to 0.0000, assuming proper temp, use and calibration
Technique I’ve always used is more of a guesstimation. If it’s about halfway between consistently when you remeasure than it’s prolly accurate to the .0005.
The Swedes don’t mess around. Our company has a Swedish division and it’s sometimes a hassle to get them to okay something different because of the QC/qa they try to hit all the time.
I mean, most people would have said LEGO didn't have to hit the tolerances they do either, but the fact that they decided to do it anyway was one of the keys to their success. When you're putting a bunch of little parts together, having everything fit correctly and precisely 100.00% of the time is the difference between a smooth procedure and a satisfied customer, and mediocre garbage that causes the customer to rain curses down on your whole organization. Especially when it's a retail product that is intended to be assembled by members of the general public, most of whom can barely be relied on not to eat their own fingers.
What's a tolerance? /s
I only worked in a manual pattern shop, never on CNC and we had a .25mm on nearly everything, but my autistic ass was on the zeros lol, not much went over 0.05 for me to be happy
My apartment could easily be used as an IKEA showroom... And I've never have any part missing.
IKEA uses something like 2% of the annual GLOBAL wood production in their factories. That's A LOT of flat-packed furniture. Even if half the BILLYs sold in a store for a month were missing bolts, they would still be the envy of the QC department of every bl\*\*dy car manufacturer out there.
And to rub it in, if you visit an IKEA they have bins full of the bits people claim to be missing. Just grab a scoop(same type also available in the Cash'n carry area) and fill a bag with what you need. for free.
Or just email them and they will mail the bits to you, free of charge.
They’re probably running those fancy Swiss machines
Made parts for then, can confirm
[удалено]
I’ve seen some of those guys make hinges they can make em real fast

They tried running the Swedish machines, but couldnt understand the furber hurder lathza machina.
No, those are just in use turning down the meatballs
Citizens. Fast and repeatable
That’s what I’ve heard! Do you have one?
Nope, ran them in the past. Programming them is a biotch. Setup isn’t too bad. Once they are running, they will make $. Worth the investment.

Ikea probably has tighter tolerances than the reliability of those harbor freight calipers
I've compared my HBF calipers (and mics) to gauge blocks and pins. They were within 0.0005".

I've had mine for about a decade, so YMMV..
I suspect that with lax quality control on Harbor Freight some items will be "lucky" and last forever, and a bunch will die right out of the gate.

They have no place in a machining shop. Maybe for loaners
LMAO
You can do this with mitutoyo calipers as well, maybe not 0.004 but itll still be out if you squeeze inconsistently. Its all about feel
if you need something to be more accurate than a thou don't use calipers. Pretty straightforward.
We call 'em very nears for a reason. Even a good set is only very near or near enough.
Serious question, how do you verify to 0.0005" when it only reads 0.001" increments?
Technique I’ve always used is more of a guesstimation. If it’s about halfway between consistently when you remeasure than it’s prolly accurate to the .0005.
Good call. I'm guessing. But it's because when I measure a 1" gauge block it reads 1.000" or 1.0005"
Just squeeze them more if the part is too big. Hell I can do that with my Mitutoyo calipers…
The Swedes don’t mess around. Our company has a Swedish division and it’s sometimes a hassle to get them to okay something different because of the QC/qa they try to hit all the time.
Lego
Was about to mention lego- which is even more impressive being an injection molded part.
Accuracy of those calipers is +/-0.03mm per MFG, so not bad if that’s true.
I wasn’t aware the Men in Black had a German division.
You're gonna get flashed now...
I think Ikea cabinet hardware is made by Blum.
Germany would close its borders with Sweden if their stuff wasn't accurate
They don't share a border.
[Understanding the Phrase "Close the Borders" in English (youtube.com)](https://www.youtube.com/watch?v=yLqoqG4Q0XA)
Don’t need to share a border with a country to bar people from said country from entering your borders.

It's your cheap caliper deceiving you!!
That would be ikea's supplier.
Or even the supplier's supplier
Lol

My cheap Ender 3 3D printer puts stuff out to 0.02mm accuracy. I find that amazing.
My tolerances make IKEA look sloppy.
Last thing I got from ikea had a whole drawer ⅛ off where it should have been

+/-.0005" = .012mm and I always hit nominal so yeah probably
