Horses for courses. We make short hex wrenches and we make these longer ones. Sometimes you need the leverage, sometimes you don't. And sometimes you have the wrench you're looking for and sometimes, somehow, it's gone.
Why buy a whole new set? We've made our hex keys (most formats) available individually so you can get just the size(s) you need.
They're made of chrome-vanadium steel and hardened & tempered so they'll last until the shop gnomes steal them again. We nickel plate them for corrosion resistance, and like nearly everything with the Unior name on it, they're proudly made in Europe.
