Original Design of Notch-free Nut Prevents Vibration and Noise

Vibration at high speeds is eliminated by a notch-free nut which offers superior balance and concentricity. This ideal nut design not only eliminates whistling noise and coolant splattering, but also assures increased strength of the nut itself.



Easy and Firm Clamping with the Mega Wrench

The Mega Wrench has a uniquely designed one way clutch
system with a roller bearing and ratchet function and is capable of safely and evenly applying force on the entire nut periphery.



Digital Mega Torque Wrench

Digital Mega Torque Wrench is used for the secure and appropriate tightening of collet chuck nuts to their recommended values.
