Pneumatic screwdriver tool powered by compressed air, specifically designed for screw tightening operations. This air-driven tool is used for bolt and nut tightening and loosening tasks in manufacturing assembly operations. Unlike air impact wrenches, it features precise torque control and low-speed rotation, making it suitable for electronic component and precision machinery assembly. Equipped with clutch and torque adjustment functions to prevent over-tightening. Optimal for continuous work in automotive production lines, electronic equipment assembly, and precision machining facilities. Characterized by lightweight design, excellent noise reduction, and minimal fatigue during extended use. Clearly distinguished from air drills and air grinders in terms of application.
