  • High quality
Style: SAE & Metric
I was sick of the small little unlabeled cheap Allen kits from big box stores so I splurged on these and havent regretted it for a second. These are SO much nicer, easier to identify the size, easier to use because of the length, super well made, and the storage solution of having them in the holder is amazing. ... show more

  • Impressive quality from klein.
Style: SAE & Metric
A+ quality from klein on this one. These are definitely the nicest allens I've ever used. I was not expecting such quality, but they have very little flex, the case is nice, and the color coating makes things incredibly convenient when you fullly familiarize yourself with what is what. I would recommend this product to anybody if it's within their budget. This isn't your typical 'klein tier' tool. In the world of pliers, cutters, etc.. Klein is generally considered the acceptable tier option for pros. Whereas brands like Knipex, and even Icon from harbor freight outshine them as far as the upper end quality goes. Not these, these are very quality. ... show more

  • These things are bigger than I expected …in a good way
Style: SAE & Metric
I know, Klein tools. I know they’re always well-made, but these hex wrenches are actually longer than I expected. They are fantastic pleasantly surprised, and the color coding is really a great feature.

  • Great tools but they are big

Great quality and strong but these are surprisingly large and heavy - not the typical for sure.

  • Perfect for My Purposes
Style: Metric
I recently got into 3D printing, and it turns out, I got a bit of a lemon of a machine. Because I have had to disassemble and reassemble the extruder quite a few times, it’s come to the point that the cheap Allen keys included with my printer are stripped and won’t work anymore. That was when I realized my husband had somehow never bought a sturdy set of Allen keys for our home toolset. I decided that even though I only needed a few smaller sizes, I wanted to get a decent sized, sturdyset for our toolbox, and when I saw the colors, I couldn’t resist. They’re perfect, I love them so much. They’re much heavier duty than the tools I had been using, and definitely I feel like I got my money’s worth. My tasks (which came up again right away after the tools arrived!! Good timing) were much easier with these superior tools. The included holder is cool, but it is quite difficult to slide them in and out, so it’s not really useful for someone who is frequently pulling their tools in and out on the job. I just keep the two smallest sizes out with my 3D printing tools, and put the rest away in case a need ever arises in the future where we need a larger size. I have had some of the logo on the tools scrape off right away, but it was only the brand name, not the size, so it hasn’t bothered me. Thankfully the color coding will keep them identifiable even if the lettering does all come off (I don’t think it will, the brand logo seems slightly different). ... show more

  • Great hex keys for the newly divorced or separated!
Style: SAE & Metric
My wife left and I bought these. Was definitely the right move. I like the colors and they’re really good at taking things apart or putting them together.
