Klein does it again
These are heavy duty and designed very well. They are also very large in size which I was not expecting. They are easy to hold onto and are quite versatile. For context, I work in IT and have used these a few times for installing monitors on dental arm mounts and they have worked flawlessly. Definitely worth the money. Klein is my first preference for tools in general because they have been consistently high quality tools for a great value. They also tend to have options that are more aligned with what I am looking for instead of having to buy a larger kit than I need or buy separate kits to get what I need.

It's big, beefy, and solid tool to use.
Great tool, it's big, sturdy, and solid hex wrench multi-tool. Used this to assemble a big and didn't have any issues, Easy to grip and didn't slip or cause me to mess up. Would recommend.

All Your SAE Hexes in One
This is a surprisingly large hex set. That said, it's an extremely sturdy hex set. I don't think I could torque out the frame or the individual drivers before I start stripping bolts. The black finish didn't last the first bolts turned, but the metal underneath is completely unmarred. This thing has every size of hex head I've ever seen, and a couple that I haven't, ranging from diminutive to gargantuan. There's no locking feature, but it has solid enough tension that it doesn't really need it.

Heavy duty
Leave it to Klein to keep the bar high the set I purchased is exactly what it states PRO the large handles give you the torque you need for any task this cuts down on needing to carry extra tools (a ratchet and bit ) and saves time not having to run back and forth the long arms reach into all those places that traditional arms just won’t work,also having both SAE and MM (which Old Red doesn’t have) saves money on purchasing odd ball tools that may not match your existing set of tools wether you are a hobbyist mechanic electrician or other professional this heavy duty set is the last set you will ever need and as a side note the Pro line also comes in Torx , so make sure you notice the difference in the regular (which is also great )
