basic information
Primary tightening wrench exclusively for high-strength bolts. With the torque adjustment knob (equipped with a locking mechanism), the tightening torque can be set according to the size of the bolt being tightened. The torque adjustment knob features a locking mechanism to prevent unexpected setting shifts during work. It includes a bolt axis rotation prevention mechanism (nut rotation type) that fixes the bolt axis during tightening, allowing the nut to rotate preferentially. By incorporating a new high-rigidity aluminum body and a double-insulated motor, it achieves a double insulation structure, ensuring the safety of the operator. Since it does not have a striking mechanism like an impact wrench, it allows for low noise and low vibration operation. ● Compatible bolt sizes: High-strength primary tightening M16, M20, M22, M24 (S10T) ● No-load rotation speed (min-1 [rpm]): 110 ● Power supply (V): Single-phase 100, Single-phase 200 ● Maximum power consumption (W): 1350 ● Body weight (kg): 4.1 In addition, we offer a wide variety of options. ● For more details, please contact us or visit our website or web catalog.
