I just got a Typhon Mega and Outcast 4S, and I've been really happy with these hardened hex drivers. I use them in the 1/4" socket of an electric screwdriver, or my Gerber Armbar pocket knife when I need fine control.
The trucks come with a combo wrenches that handle all the different types of nuts on the truck. They come with allen wrenches too, but the hardened wrenches are far superior.
