From travel kits to garages to professional shops, the hex wrench is a staple. And while a 5/32" key received with self-assembly, particle-board furniture can tighten a 4mm hex in a pinch, the chrome-vanadium steel and ball-end of Topeak's T-Handle DuoHex is a much better tool for the job.
When it comes to precision instruments like our bicycles, the quality of tools is equally important. Topeak's DuoHex Wrench Set covers 2 through 6mm fasteners with a hexagon cross-section that provides excellent purchase and helps prevent dreaded rounding or stripping of screw heads. The DuoHex features a plastic handle that eases strain for full-time technicians, and a ball-end that not only helps speed threading and limit torque, but provides access to otherwise inaccessible fasteners.
A final note that highlights Topeak's attention to detail in the DuoHex Wrench Set is large, easy-to-read size markings for quick identification.
