What does MEGA mean?

All MEGA collet chucks have a notch-free MEGA nut that prevents vibration and reduces noises. The collet chucks are tightened by a unique MEGA wrench that has a one-way clutch system with roller bearings and a ratchet function, which is capable of safely and evenly applying force to the entire nut periphery.
