Time to replace some pedals. Where's the 8mm?
Seriously. Where is it?
It's an unfortunate truth that, despite the best organizational practices, tools go missing. And it always seems to be the one you need right now.
When one does go missing 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 we're the only player in the bike tool game to produce hex wrenches certified to ISO 2936, the international standard for metric hex key sizing. These are, like nearly everything with the Unior name on it, proudly made in Europe.
