For production fastening where a slow, controlled rundown is preferred and surrounding components limit direct tool access, the Ingersoll Rand QA1L02S4LD Angle Air Nutrunner combines 250 RPM free speed with a 3.5 to 56.4 in-lb torque range and an adjustable shut-off clutch. The angle configuration helps operators approach fasteners around housings, brackets, fixtures, and closely arranged components, while automatic clutch shut-off provides a defined endpoint for repetitive tightening cycles.
The Ingersoll Rand QA1L02S4LD operates at a deliberate 250 RPM, making it a suitable choice for compatible assembly processes where controlled fastener rundown takes priority over maximum cycle speed. Its adjustable 3.5 to 56.4 in-lb torque range accommodates a range of fastening requirements within the tool's specified capability. When properly adjusted on the actual production joint, the shut-off clutch automatically stops the nutrunner at the preset torque point to support consistent fastening from cycle to cycle.

Applications:
- Precision-oriented production assembly — completing compatible fastening cycles where a slower rundown rate supports greater process control.
- Automotive component assembly — tightening fasteners located around brackets, housings, fixtures, and closely positioned components.
- Equipment and appliance manufacturing — reaching fastening points within frames and assemblies where straight-line tool access is restricted.
- Electrical and electromechanical production — performing controlled fastening inside cabinets, equipment assemblies, and compact component layouts.
- Fixture-based workstations — accessing recessed or side-oriented fasteners while maintaining adjustable shut-off within the specified torque range.
FAQs:
- Q: What torque range does the Ingersoll Rand QA1L02S4LD provide?
A: The specified torque range is 3.5 to 56.4 in-lbs. Establish the appropriate clutch setting on the actual production joint according to the fastener, joint characteristics, component materials, and assembly requirements. - Q: When is the 250 RPM speed useful?
A: The low operating speed provides a more deliberate fastener rundown than higher-speed configurations. It can be useful for compatible assembly processes where controlled tightening takes priority over minimizing rundown time. - Q: What does the adjustable shut-off clutch do?
A: The clutch allows the tool to be adjusted within its specified torque range. When the preset torque point is reached, the nutrunner automatically shuts off to provide a controlled endpoint for the fastening cycle. - Q: How does the QA1L02S4LD compare with the QA1L05S4LD?
A: Both supplied models have a 3.5 to 56.4 in-lb torque range, but the QA1L02S4LD operates at 250 RPM while the QA1L05S4LD operates at 500 RPM. The 250 RPM model provides a slower rundown rate for applications where more deliberate fastening is preferred. - Q: Should fastening results be rechecked when production conditions change?
A: Yes. Changes to fasteners, joint materials, drive tooling, component conditions, or compressed-air supply can affect fastening results. Recheck the clutch setting on the actual production joint and verify completed fasteners according to the required quality-control procedure.
