All models adopt push-trigger start design: the tool runs when pressed down and stops immediately when lifted, with no extra trigger operation required. The simple and intuitive operation logic reduces the learning curve and greatly improves work efficiency of fastening stations on assembly lines, fitting high-cycle mass production assembly needs.

The full series offers 12 specifications with torque coverage from 1 to 280 kgf・cm, adapting to fastening needs from micro screws to large-size screws. Based on the clutch-type torque principle, it automatically disengages when preset torque is reached, with ±3% control accuracy. It effectively prevents over-tightening, thread stripping and workpiece damage, ensuring consistent fastening quality across batch products.

Built with high-quality pneumatic motors and precision clutch 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 & maintenance costs.

The body is compact and lightweight: low-torque models weigh only 540g, and high-torque models also maintain reasonable weight. The comfortable grip reduces hand fatigue during long continuous fastening operations, effectively reduces occupational strain for operators and improves workstation comfort.

All models support fastening of both machine screws and self-tapping screws, flexibly adapting to different workpiece requirements. It is widely used in electronics assembly, home appliance assembly, toy manufacturing, hardware & plastics, mold parts and other industries, serving as standard pneumatic tools for mass-production precision fastening.
