Built for light-torque assembly work where access and repeatability matter, the Cleco 19RAS03AM2 pneumatic stall collar reverse-angle nutrunner combines a compact 90-degree head with a 1,700 RPM free speed for quick run-down on small fasteners. Its 2.3 ft-lbs / 3.2 Nm maximum torque is suited to controlled fastening on soft-draw applications, where the joint pulls down gradually rather than stopping abruptly. The stall mechanism (the tool stops rotating when fastener resistance reaches the available air-powered torque) allows torque output to be adjusted by regulating air pressure, making this tool useful for assembly stations that need simple pneumatic torque control without an automatic shut-off clutch.
The collar reverse configuration lets operators change direction at the tool for removal or rework, while the lever start provides straightforward throttle control during repetitive fastening. With a 1/4" square drive, 11.4" overall length, and 0.36" side-to-center distance, the 19RAS03AM2 reaches into tight fixtures, brackets, appliance assemblies, and component housings where a straight or pistol-style nutrunner may not fit.

Features:
- Stall-type torque control supports soft-draw fastening applications where torque builds progressively through the joint.
- Torque can be adjusted by changing regulated air pressure, giving production teams a simple way to tune output for the fastener and joint.
- Compact angle head improves access around fixtures, panels, brackets, housings, and other confined assembly areas.
- Collar reverse allows the operator to switch direction for fastener removal, correction, or rework without changing tools.
- Lever start provides direct throttle control for repetitive station work and short-cycle fastening.
- Lightweight 1.3 lb body helps reduce hand strain during frequent small-fastener assembly tasks.
- Grip material is tested to withstand a range of industrial chemicals encountered in production environments.
- Standard equipment includes operating instructions, service manual, and suspension bail.
Made in USA: 
Applications:
- Light assembly stations — running down small bolts and nuts on brackets, covers, panels, and subassemblies.
- Appliance and equipment manufacturing — fastening in recessed areas where the 90-degree head improves reach.
- Automotive and transportation component assembly — controlled low-torque fastening on trim, housings, and small mechanical components.
- Electronics and enclosure assembly — tightening hardware on cabinets, frames, and access panels where over-torque can damage parts.
- Maintenance and repair benches — removing and reinstalling small fasteners during service, inspection, and rework operations.
FAQs:
- Q: What does a stall nutrunner do?
A: A stall nutrunner continues running until fastener resistance reaches the tool’s available torque, then the motor stalls. The operator releases the lever after the stall point and removes the tool from the fastener. - Q: How is torque adjusted on the Cleco 19RAS03AM2?
A: Torque is adjusted by regulating the air pressure supplied to the tool. Because line pressure affects output, this tool should be used with a properly sized air regulator and stable compressed air supply. - Q: What does “collar reverse” mean?
A: Collar reverse means the tool direction is changed using a collar-style reversing control. This allows the operator to switch between tightening and loosening without changing to a separate removal tool. - Q: Is the 19RAS03AM2 a good choice for tight spaces?
A: Yes. The compact right-angle head, 1.06" head height, and 0.36" side-to-center distance help the tool reach fasteners near walls, edges, fixtures, and assembled components. - Q: Is this tool intended for high-torque bolting?
A: No. With a 2.3 ft-lbs / 3.2 Nm maximum torque rating, this model is built for low-torque assembly fastening, not lug nuts, structural bolts, or heavy equipment repair.
