Ingersoll Rand 41PA8PSQ4 Pneumatic Screwdriver is designed for repetitive fastening applications where precise torque control and dependable shut-off performance are required. This 800 RPM pistol-grip screwdriver uses a push-to-start actuation system and an adjustable shut-off clutch with a maximum specified torque range of 15–100 in-lbs, depending on clutch setting. Its balanced design, comfortable grip, and quick shut-off make it well suited for fastening plastics, composites, and metals in production environments.
The 41PA8PSQ4 combines adjustable torque control with a 1/4" hex quick-change drive for efficient bit changes. Its one-handed reverse lever provides convenient directional control, while the adjustable shut-off clutch and quick shut-off help support precise fastening and reduced air consumption. The tool operates at 28 CFM air consumption through a 1/4" NPT air inlet and produces a published 78 dBA sound level.
