A comprehensive set of thread guages for metric and sae bolts and nuts. It's housed in a neat display case that provides easy of use as bolts can be tested without removing individual guages. All guages are aluminium so the entire kit is very light.
Each guage has thread and type clearly labeled on the side making it easy to store them in order - see the examples of coarse, medium and fine m10 threads in the second picture.

I am so happy. i have wanted a set like this since i was a child going to the hardware store with my dad. but it didn't exist that many years ago. well i got to use this already day one, and it already saved me from purchasing a wrong sized nut for a second time.

This is a very nice set, and compact. it arrived fairly quickly, faster than all the other items in my order with other sellers. i will say this is a very high quality set, i didn't see a single flaw, and some of these pieces are tiny, so they did a great job with this set. it's super lightweight too. i believe the price here is very fair, i recommend this seller as well as this set. i reached out to them to see if this could be shipped quickly as i needed it, and they were expecting production to set the shipment date back a little, but it ended up shipping out a day or 2 later. i am very pleased with this purchase, excellent quality. if your considering buying one of these, i would say do it.
