  • Surpassed my expectations.....a must in any tool box.

I looked around and saw a lot of different versions and realized this one had a good value. When I received this item I was pleasantly surprised to find a professional quality thread checker that I will be able to use for good. Highly recommend it!

  • Not every size

It's very handy if it has the sizes you need. M9 is a common guitar pot nut size, and this device goes from M8 to M10, no M9. Just be sure it has the sizes you're needing.

At least 2 of the studs, one sae and one metric were bent. I was able to straighten them though. Good quality, but better packing is advised.
