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.

Has taken years of abuse and can still take more
I've had the same one for years now and its held up tremendously well. I thought the plastic body would've atleast cracked by now, and even after dropping it off the tops of 8', 10' and 12' ladders numerous times, it still hasnt. Surprisingly durable for a plastic klein tool.
