The Nubhex driver set was put together because on occasion it becomes a pain to work in tight areas where a normal hex wrench doesn't fit or is cumbersome to try to use a normal-sized wrench like mounting water bottle cages on your frame.
 
Comes in a set of 3 of the most common sizes for bicycle repair work  3mm,  4mm, and 5mm.  Each is Nubhex is brightly color-coded (Orange, Red, and Bright Green) to help you pick the right tool and to help you find the tool when you inevitably drop it and have to look for it.

Though the Nubhex is designed to be very sturdy and you can put a good amount of force onto a bolt these are not designed for extreme torque situations where you should be using a torque wrench anyway
