It adopts semi-automatic operation logic: start by pressing the lever and stop immediately upon release, with fast start-stop response. Operators can precisely control operation timing, making it ideal for assembly scenarios requiring alignment and fine adjustment. The comfortable operating feel reduces fatigue during long work hours, balancing work efficiency and operation controllability.

The full series offers 12 specifications with torque coverage from 1 to 280 kgf・cm, adapting to everything from micro precision screws to large-size fasteners. Each model matches different speed and screw fastening capabilities, allowing users to select the precise model based on screw specification and work cycle to fit different production line needs.

It adopts a precision clutch-type torque structure that automatically disengages and slips when preset torque is reached, with stable torque control accuracy of ±3%. It effectively prevents thread stripping, workpiece cracking and screw breakage caused by over-tightening, ensures consistent fastening quality across batch products, and reduces defect rates.

Equipped with high-quality pneumatic motors and precision transmission components, it delivers stable and reliable operation with long service life. Excellent noise control (max 78 dBA) improves the workstation environment. Driven by standard air pressure with economical air consumption, it is suitable for long continuous operation and greatly reduces production line operation and maintenance costs.

The body has balanced weight distribution, and the grip area features a non-slip comfortable design, reducing hand fatigue during long handheld operation. The compact structure with body diameter fitting hand grip enables flexible and intuitive operation, effectively reduces occupational strain for operators and improves workstation comfort.
