Cleco 19RAS05AM2 Pneumatic Stall Collar Reverse Angle Nutrunner | 19 Series | Lever Start | 850 RPM | 3.8 (ft-lbs) Max Torque

Built for controlled low-torque fastening in tight assembly areas, the Cleco 19RAS05AM2 pneumatic stall collar reverse angle nutrunner pairs a compact 90-degree head with 850 RPM free speed for steady fastener run-down where access is limited. Its 3.8 ft-lbs / 5.2 Nm maximum torque provides more torque capacity than the faster 19RAS03AM2 while keeping the tool in the light assembly range for small bolts, nuts, and component hardware. The stall-clutch style (the motor stops when joint resistance reaches the available torque) provides production teams with a simple pneumatic fastening method for soft-draw joints, where gaskets, washers, plastics, or layered parts are compressed during tightening.

The collar reverse control allows direction changes at the tool for loosening, correction, or rework, and the lever start gives the operator direct throttle control during repetitive fastening cycles. With a 1/4" square drive, 10.6" overall length, 1.06" head height, and 0.36" side-to-center distance, the 19RAS05AM2 is well suited for fixture work, enclosed assemblies, appliance production, transportation components, and maintenance benches where a pistol-style or inline tool cannot approach the fastener cleanly.

Features:

• Stall-type fastening supports soft-draw applications where torque rises as the joint compresses.
• Torque output can be adjusted by changing regulated air pressure, making setup straightforward for repeat assembly work.
• Compact angle head provides access around tooling, housings, panels, brackets, and other close-clearance work areas.
• Collar reverse lets the operator switch between tightening and loosening for rework, removal, or correction at the station.
• Lever start gives direct control during fastener engagement and release, especially in short-cycle production tasks.
• Lightweight 1.19 lb body helps reduce handling fatigue during frequent low-torque fastening operations.
• Grip material is tested to withstand a range of industrial chemicals commonly found in assembly environments.
• Standard equipment includes operating instructions, service manual, and suspension bail.

Applications:

• Assembly fixtures and workcells — tightening small fasteners where the tool must reach around tooling or adjacent components.
• Appliance and cabinet production — fastening covers, panels, housings, and brackets without relying on bulky straight tools.
• Automotive and transportation component work — installing light hardware on interior parts, trim assemblies, enclosures, and subcomponents.
• Electronics and equipment manufacturing — controlled low-torque fastening where overtightening can distort parts or damage threads.
• MRO and repair benches — removing and reinstalling small bolts and nuts during inspection, service, and rework procedures.

FAQs:

• Q: What type of fastening work is the Cleco 19RAS05AM2 best used for?
  A: This model is best used for low-torque assembly fastening on small nuts and bolts, especially where the fastener is tucked into a corner, fixture, or housing. It is not intended for high-torque bolting or breakaway work.
• Q: How does a stall nutrunner differ from a shut-off nutrunner?
  A: A stall nutrunner stops when the motor reaches the available torque output, while a shut-off nutrunner uses a clutch that automatically shuts the tool off at a preset torque. Stall tools are simpler and useful for many soft-draw applications, but shut-off tools are usually selected when tighter torque repeatability is required.
• Q: How is torque controlled on this model?
  A: Torque is controlled by adjusting the regulated air pressure supplied to the tool. For consistent results, use a stable compressed air supply and verify final torque with the plant’s normal torque-check procedure.
• Q: What does the 1/4" square drive fit?
  A: The 1/4" square drive accepts compatible 1/4" drive sockets and extensions. Always match the socket to the fastener size and confirm that the socket is suitable for powered assembly use.
• Q: Why choose the 19RAS05AM2 instead of the faster 19RAS03AM2?
  A: The 19RAS05AM2 trades speed for more torque capacity, offering 850 RPM and 3.8 ft-lbs maximum torque. Choose it when the application needs more tightening force than the 2.3 ft-lbs model but still requires a compact 19 Series right-angle tool.
