  • 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 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.

  • 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

  • This is a fine addition to my tools.
Size: 30 Thread Checker Color: Red
This will be so handy with both SAE & metric sizes. A Nicely made all metal device [not plastic]. It's already solved an irritating nut problem. A tiny 6-32 dillemia quickly & easily rectified for a porch light cover. Brass knurled nuts promptly acquired & installed.

  • Valuable tool
This helped me organize a bucket of random hardware. Accurate and well-labelled. Some of the threads feel weak so be careful with dirty bolts and don't use too much force.
