Don't waste your money on this poor quality product. Check all sizes to make sure correct. I'm missing 2 sizes and those spots we filled with a repeats.

I have quite a collection of nuts & bolts, but sometimes finding what I need is like finding a needle in a haystack. The other problem is finding the perfect nut or bolt but not knowing what thread it is to go buy more like it. Those problems go away with this set. Unlike the fixed boards in the hardware section of the local home store, you can take these where they’re needed, like under a car or on a piece of equipment. Plus, they store neatly and safely in the included rugged case!

Very handy sizing kit - love how it is all self-contained in the snap-close container. Has pretty much every size I have needed to check (I work on cars a lot). The pieces seem to be perfectly sized/calibrated for anything I have tested with it. The case is sturdy and is about the same size as a smaller powertool - like an air trim nailer. So it stacks up nicely with my other tools in cases.
