Built for high-precision assembly applications where repeatable torque control is essential, the Ingersoll Rand QA8ASRS040NF41S08 Inline Air Nutrunner delivers a 14.8–29.5 ft-lbs (20–40 Nm) torque range with a 540 RPM free speed and a 1/2 in. square drive. Its inline configuration keeps the tool aligned with the fastener for improved control during repetitive fastening operations, while the remote start design allows seamless integration into automated assembly systems and production workstations. This QA8 Series nutrunner is well suited for manufacturing environments where fastening consistency, productivity, and torque accuracy are critical.
The QA8 Series features a precision shut-off clutch that automatically disengages once the preset torque is reached, helping improve fastening repeatability while minimizing the risk of over-tightening. Its durable air motor is engineered for continuous production use, and the compact inline housing provides excellent accessibility in confined assembly areas. The 1/2 in. square drive accommodates a wide range of industrial sockets for medium-torque fastening applications.
