Specification

AW drive system:

Enhanced torque transmission

Longer life

Optimum centring

Better mounting output thanks to fatigue-free screwing in; the required contact pressure for transmission of the torques is considerably lower

Largest possible contact surface of bit in screw drive

Even force distribution prevents damage to the surface-protection coating and therefore ensures better resistance to corrosion
