These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects and well as any wobbling that may occur. There profile is such that they're a little springy in the X Y & Z linear axis but not in the rotational axis. That means you can enjoy flexibility without increased backlash making them suitable for precision CNC work. 

This coupler will connect a 5mm diameter shaft to an 12mm diameter shaft. A perfect add on for our stepper motors. Comes with two sets of double set-screws (two per side) for secure attachment. You'll need an allen wrench to tighten/loosen the set-screws.
