Great set, good value. Review: Make sure you read end..good product and company - I left my formerly negative review mostly intact below, just to explain the negatives of the aluminum case. However, after being annoyed by the aluminum case for over a year, I finally called Accusize. I got a very helpful person immediately, no long hold or call back. I explained my problem to her, she suggested sending me the plastic case for free. (I had thought about trying to buy one, but free is OK, too.) She followed up with a couple of emails about the shipping, and I got the plastic case, which is nice. No stuck pins, seems pretty tough and well made. Thank you, Livia. I should have called sooner. So, now it gets five stars, like most of the other Accusize things I have. But now, I dealt with the company, and it went well. It is now common that it is near impossible to speak to a human, so this was a nice surprise. If it is still available, I would not get the aluminum case, unless they have changed it. OLD REVIEW FOLLOWS, NO LONGER APPLIES--> This bad review is for the 0.251 to 0.500 set. I also have the smaller sizes, and they are fine. Gage pins themselves are ok..sharp edged, but I can change that if I want, and the sharp edge could be needed in some situations. However, the case is bad. The holes are through a sheet of plastic with foam underneath. The holes in the foam are way undersized..some practically seem glued in. I'm an avid motorcycle woods rider, and from that have what is probably stronger than average grip strength. Most of these I cannot get out without time consuming "wobbling" to enlarge the hole in the foam, then pulling,, wobble,, pull.. it can easily take a minute to remove one. It shrinks back after a while, too. Really makes me mad. Should I grab my new gage pins with pliers? It is annoying enough that I might make a wood piece with holes. I shouldn't have to drill 250 holes to use this stupid set of pins. I'd recommend considering another brand. I've been happy with other accusize things, mostly tooling, but not this junk. Should have returned it. 250 small slick things that are only useful if in order and easily accessible. And they aren't. The case is an important part of this product, and it is terrible.<--OLD REVIEW, READ FROM START. ## Features - Class ZZ.

The price point of these pins, one cannot expect an individual inspection report on each pin. The pins have measured accurate as I can measure them and have been at stated sizes. For my home machine shop use they exceed expectations. I am working within .0005 tolerances and they are doing what I need them to do. Nicely packaged and really corrosion proofed for transit. Each pin wrapped in oil paper to protect. Fit and finish is quite awesome for the price. Very happy with my set. Looking to get next size group of pins (.251-.500) from Accusize. I hope this helps. **Q: If i want to buy only 1 set , should i buy plus or minus pin gage set ? which set experience machinists prefer ? why ? thank you so much** A: According to CCROSS: "A pin gauge set will typically consist of either plus or minus pin gauges, and based on procedure or tolerances may require both versions to determine a go no go outcome. A minus pin gauge set includes pins with a specified tolerance below the target size, allowing the pin to fit within the target dimension. Likewise, a plus pin gauge set includes pins with a specified tolerance above the target dimension, creating a no-go situation for a bore at the target dimension." So, choose the minus or the plus based on your work. **Q: What is the size of the box these pins are in?** A: Box size 4" x 5", each pin has a cap to hold onto each pin. **Q: Are all new sets coming in the new improved case?** A: As of writing, we are still in the process of upgrading the cases. So some of them might come with old cases. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Accusize Industrial Tools - 190 Pc Precision Minus Class ZZ Pin Gauge Set *by M***1 on April 10, 2026* A little wax paper and preservative to deal with, but absolutely worth the effort.
