Feature 2
Vacuum head integrated into the main body (Option)
・Easy to install vacuum head to tool body
・Vacuum head tip designed to screw shape (replaceable tips)
・Supporting multi-materialization of small screws (corresponds to non-magnetic threads such as stainless steel
and carbon)

Vacuum head made ofrust-resistant stainless steel

Feature 3
Torque accuracy unaffected by robot operation
・Minimizing the effect of external force on torque accuracy by integrating a torque transducer into the tool

Feature 4
Ultra-low torque detectable
・Providing highly accurate tightening by using low-inertia servo motor
・Detecting Screw rotation angle by using built-in resolver
・Displaying torque with high resolution, 0.001 Nm
