6-Inch Vernier Caliper Measuring Tool

Love this tool. It sits on my desk and I use it almost daily, often several times a day when i do use it. it is accurate, battery free, solidly built, and looks good. Precise is the way I would describe this tool!

Most of the other reviewers complains about various issues with this caliper: accuracy, oily, possibility of rust, roughness of edges. All right complains, but they need to be put in perspective. If you are considering the purchase of a vernier caliper you know at least something about mechanics. How many parts made such a device? Building that many, with highest quality material, to the highest possible standard for accuracy (hence sharp) on one side of the part (the "internal") and for user friendly (hence smooth) on the other side (the "external") cannot be made cheap. All manufacturing procedures have tradeoffs. So for the price, this is an excellent product. Is it accurate enough? Yes, mine is accurate to the level of the vernier scale, however a tiny bit wobbly at that level, hence one less star in accuracy. Easier to read. Is it oily? Yes, but for most use that's minor problem. Is it rusty? No, but the manual says that if you clean the oil completely it might become so. Is it smooth? No, it's a bit sharp. If I had time to spare and would use it more often than I do, I'd try to smooth it with a file. But for occasional use it's totally usable. At this price, it totally deserves five stars. Granted, if you compare it with a similar one costing 10x its price, it would barely get two stars, perhaps it'd get even just one. But that would be an unfair comparison, like a race between an accomplished world champion and a random kid in middle school.

Good value for the price. I bought to measure small RC bearings, axles, etc. Seems accurate enough, unless I need to measure the thickness of a small grooved object, such as the inner thickness of small screw threads. The bevel of the outer jaw is too thick (~1mm) for accuracy.

I find great value in this tool. With proper care, it should last a lifetime. I do not know why Amazon desires that I mention Battery Life; but I will say this model was specifically selected because it requires no battery, has no electronic display or any digital functionality (to fail or go out of Calibration). Best described as, "Analog baby." Accuracy confirmed against a different, trusted, 0.001 Caliper and this thing is closer than the listed specifications give it credit for. If for some reason you cannot read a labeled slide-rule, this probably won't work for you. For everyone else, this is the simple, accurate, functional Caliper that you are looking for. I will leave it to a hand model to demonstrate that the thumbscrew locking operation is excellent and smooth, it has smooth and stiff slide-action (not sloppy at all), nice probe depth and allows grip and control in use. Case and even a cleaning cloth included.

This is a high quality, durable caliper that feels solid and well-made. It slides smoothly, holds its measurement, and does exactly what it is supposed to do. It also comes in a nice protective case, which is a plus. I have no complaints about accuracy or build quality. The only thing I occasionally wish is that I had bought a version with a digital display for quicker readings. That is a preference issue, not a flaw.

Quality seems excellent. My HF digital caliper also claims 001" precision and also shows the next half-thousandth (.0005"). It matched this vernier caliper, nearly always to the half-thousandth. And two other inexpensive calipers matched this vernier caliper. The one I received seems to be built correctly in contrast to some other reviews. However - I thought I could read Vernier, I learned on pre-electronics land survey instruments long ago. But the graduations on the Inch scale are so close that I mis-interpreted the reading, about one-third of the time. And note you will need a magnifier - I use a jeweler's headband stereo magnifier - to see the reading. I would write down what I thought was the measurement. Then the digital caliper, about a third of the time, would show at least .010" larger. Back to this vernier caliper, I found a matching tic at that larger measurement that also was as perfect a match as what I had relied on. One workaround for this mis-reading is to look at the measurement on the coarse scale and estimate between the tics, for example 60% of the way to the next tic. Then go look for a perfect match on the fine scale. In the example of 60% that will be about +.014". (60% x .025" graduations). This thing is definitely Old School. No battery needed, which is why I bought it. But the need to use a magnifier to read it makes it less convenient than the modern digital one. I watched a YT video explaining a Starret (famous quality brand) vernier caliper and I see the Starret is easier to interpret. Its coarse graduations are .050" while this one has .025". And its fine scale is twice as long with larger graduations, so its easier to see where tics match. With good eyesight a magnifier wouldn't be needed. The ultra-small graduations are not only hard to read. Coarse graduations of .025" plus adding a number 0~25 from the fine scale to arrive at total measurement is more confusing than I expected and prone to error. The Starret, for inches, and the mm scale on this, are easier math to work in your head. If you don't understand this paragraph then a vernier caliper isn't for you! Overall - a quality tool but for purists. For general use go to HF and get their .001" digital caliper, and some spare batteries. Several reviews here rate that tool better than other inexpensive digital calipers. I gave up and returned this. Expand the photo at the head of this listing. (And you will need an excellent magnifier to see anything like that). Is that showing 0.670" +0.001? +021? +.022? I can't measure with thousandths precision because I can't distinguish which tick is best. I made too many errors compared to using the digital caliper which was unambiguous.

I like the simplicity of these vernier calipers. I've been using tools like this for many years. Great quality and a fair price. They have a nice rule inside the box and a nice cleaning cloth. I highly recommend this product.

Es un pie de rey con un aspecto de gran calidad. Viene presentado dentro de su caja plástica de protección, con una gamuza de limpieza y una pequeña regla (en centímetros y pulgadas) de acero. El funcionamiento es muy robusto, se desliza bien y con la suficiente firmeza que evita imprecisiones. Por el precio que tiene, me parece de muy buena relación calidad-precio. Satisfecho con la compra.

Very good product for the money. I was concerned that the accuracy would be off, but turns out it is super precise and I have been able to maker some very precise fittings using this tool. A good purchase.

Nadat ik mijn twijfels had gekregen over de nauwkeurigheid van de gemiddelde elektronische schuifmaat, weer een ouderwets model aangeschaft. Prima mee te werken, en goed af te lezen. Voelt solide aan, werkt altijd als ik hem nodig heb (geen lege batterij), en afleesbaar tot op 0,02 mm!! Onder de indruk!

Solide Ausführung des Messschiebers - Macht was es soll --> Messen :-)
