Cleco 19RAA05AM2 Pneumatic Collar Reversible Angle Nutrunner | Lever Start | 19 Series | 570 RPM | Clutch Shut-Off | 1 - 4.2 (ft-lbs) Torque Range

Built for light assembly fastening where controlled torque and compact access are both required, the Cleco 19RAA05AM2 pneumatic collar reversible angle nutrunner uses a Clecomatic clutch shut-off system, which stops the tool when the preset torque is reached. Its 12 - 50 in-lb torque range, 1/4" square drive, and 570 RPM free speed make it well suited for small threaded fasteners that need more torque than higher-speed 19 Series models while still maintaining steady rundown control.

The 19RAA05AM2 is part of Cleco’s 19 Series pneumatic assembly tool lineup and is configured with lever start and collar reverse for fastening and removal tasks at the workstation. The right-angle head helps reach fasteners near housings, brackets, panels, and other obstructed areas where inline tools cannot be positioned cleanly. With a 12.4" overall length and compact angle head geometry, this nutrunner is a practical option for repetitive production work on hard joints and soft joints. A hard joint is a rigid metal-to-metal fastening condition, while a soft joint includes compression from materials such as gaskets, washers, plastics, or seals.

Features:

• Clecomatic clutch shut-off stops the tool once the adjustable preset torque is reached, supporting consistent fastening from cycle to cycle.
• 570 RPM free speed provides a controlled rundown rate for applications where the joint requires more torque and less speed than lower-torque models.
• Collar reverse lets the operator switch direction for installing or removing threaded fasteners without changing tools.
• Lever start actuation gives direct control at the workstation during fastening, release, and positioning tasks.
• Compact right-angle head improves access around obstructions, flanges, brackets, and close-clearance assemblies.
• External torque adjustment helps technicians set the tool for different assembly requirements within the published torque range.
• Grip material is tested for resistance to industrial chemicals and helps support secure handling in production environments.
• Standard equipment includes the manual and all torque springs required to meet the indicated torque specification.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)

Applications:

• Aerospace and precision assembly: controlled tightening of small threaded fasteners in brackets, panels, housings, and access-limited assemblies.
• Automotive component production: fastening subassemblies, supports, covers, and interior hardware where repeatable torque is required.
• Appliance and equipment manufacturing: repetitive nut and bolt rundown on light-duty joints with limited approach clearance.
• Industrial workstations: torque-controlled fastening on bench, fixture, and line-side assembly operations.
• Maintenance and repair benches: removing and reinstalling smaller threaded fasteners during service work where a compact angle tool improves access.

FAQs:

• Q: What torque range does the Cleco 19RAA05AM2 provide?
  A: The tool range is 12 - 50 in-lb, or 1.4 - 5.7 Nm. That converts to approximately 1.0 - 4.2 ft-lbs, making it a light assembly nutrunner rather than a high-torque bolting tool.
• Q: How is the 19RAA05AM2 different from the 19RAA04AM2?
  A: The 19RAA05AM2 runs at 570 RPM and reaches up to 50 in-lb, while the 19RAA04AM2 runs faster at 950 RPM with a lower maximum listed tool range. Choose the 19RAA05AM2 when the application needs slightly more torque with a slower, more controlled rundown.
• Q: What does Clecomatic clutch shut-off mean?
  A: Clecomatic clutch shut-off means the tool stops when the preset torque is reached. This helps reduce over-tightening and improves fastening consistency compared with relying on operator feel alone.
• Q: Can this nutrunner loosen fasteners?
  A: Yes. This model is collar reversible, so it can tighten and loosen threaded fasteners within the tool’s intended operating range.
• Q: What air supply is required for this tool?
  A: The tool is rated at 90 PSI / 620 kPa and lists 11 SCFM air consumption. The catalog also specifies a 1/8" NPT air inlet and 3/16" minimum hose I.D.
