  • Look no further for an excellent kit!
Size: 60PCS Thread Checker Color: Red
This is fantastic. There are a lot of choices and I listed every size that each set came with and this checked off more metric sizes than others that I was looking at. There is always a chance though that it won't have the one I need but I feel pretty good about my choice. It's nice and small and appears to be well built. I have another set that is on a metal plank but it's not as versatile as this set it. The versatility was important to me and the value of the kit was excellent. It was so easy to pull out the piece and check the size of a bolt. They are very light and look to be made from aluminum. I give it 2 thumbs up! ... show more

  • Great thread checking tool
Size: 60PCS Thread Checker Color: Red
This is an excellent kit for checking the sizes of threads. Much better than the ones on a tray since you can take out an individual piece and check threads on a project. The case is great and the pieces are marked well and are accurate. They seem to be very durable and well made. This is one of those tools that saves time and trips to the hardware store. Wish I had bought this years ago. ... show more

  • Great tool!
Size: 30 Thread Checker Color: Red
This is a must have item for DIYers! Makes finding bolt/nut sizes easy and accurate. It’s well made and is a great value for the money! East to use and read. It’s light weight and fits well in a toolbox drawer.

  • Great quality gauges and nice sturdy case.
Size: 60PCS Thread Checker Color: Red
Great quality set of gauges and nice sturdy case. Very easy to read. The length of the gauges are .780 long except the two one inch gauges are 1.170 long. This is something I won't use every day at home but today I had to identify a screw and it was m6-1.0 and so much faster and easier than using pitch gauges. Where this will really shine is measuring inside threads. This is definitely worth the money. It comes well packaged in a box. ... show more

  • The right tool for a specific job.
Size: 30 Thread Checker Color: Red
This is a well-made tool, very useful for sorting that batch of miscellaneous nuts and bolts you've accumulated. However, because of its dimensions it is really only useful for sizing hardware that is loose and can be brought to the checker. If you need to size something in place, say a bolt down in an engine bay, you'll probably be better off with one of the sets with detachable pieces. For the right task, this works great. ... show more

  • Very Nice and Handy!
Size: 76 Thread Checker Color: Red
If you work with a lot of loose nuts and bolts, this is a really nice helper for organizing them. It is well-made, and based on the nuts and bolts I've sized, it is accurate. I have mine hung behind a cabinet door in my garage workshop, so it is readily accessible. Having priced out others, I believe this is a good value. Of course, it covers a lot of sizes, but not all possible sizes, but most of the common ones. ... show more
