Cleco 19RAA03AH3 Pneumatic Collar Reversible Angle Nutrunner | Lever Start | 19 Series | 1,450 RPM | Clutch Shut-Off | 0.5 - 2.5 (ft-lbs) Torque Range

Built for fast, controlled fastening on smaller assembly hardware, the Cleco 19RAA03AH3 pneumatic collar reversible angle nutrunner gives production operators a compact right-angle tool with a balanced mix of speed and low-torque control. This 19 Series lever-start model runs at 1,450 RPM, helping move quickly through repetitive rundown work while the Clecomatic clutch shut-off system stops the tool at the preset torque. With a 0.5 - 2.5 ft-lbs torque range, it is suited for light bolted joints where over-tightening can strip threads, deform small parts, or create rework.

The 3/8" square drive accepts compatible sockets for light assembly fastening, while the right-angle head helps reach fasteners near panels, housings, brackets, and frame edges. Collar reverse allows quick direction changes for fastener removal or correction, and lever start gives the operator controlled actuation after the socket is properly seated on the fastener.

Features:

• Clecomatic clutch shut-off stops the tool when the preset torque is reached, supporting repeatable fastening in production assembly.
• 1,450 RPM free speed provides efficient rundown on small fasteners without moving into the highest-speed range of the 19 Series.
• Right-angle configuration helps operators access fasteners close to housings, panels, brackets, and other assembly obstructions.
• Collar reverse allows quick switching between installation and removal for rework, correction, and service tasks.
• Lever start gives the operator controlled engagement after the socket is positioned on the fastener.
• 3/8" square drive accepts compatible sockets for light bolting and nutrunning applications.
• Grip material is tested to withstand a range of industrial chemicals commonly found in manufacturing and maintenance areas.
• 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:

• Light production assembly — tightening small bolts and nuts where clutch shut-off helps maintain consistent torque results.
• Appliance and equipment manufacturing — fastening panels, covers, frames, brackets, and component mounts.
• Aerospace and transportation assembly — reaching compact fastener locations where a straight inline tool may not have clearance.
• Automotive and vehicle component work — installing light brackets, interior hardware, and small service fasteners.
• Industrial maintenance and MRO — removing and reinstalling smaller fasteners during machine adjustment, bench repair, and equipment service.

FAQs:

• Q: What is the Cleco 19RAA03AH3 used for?
  A: The 19RAA03AH3 is used for low-torque fastening where access and repeatability are important. It is a good fit for small assembly fasteners, light brackets, panels, covers, and compact bolted joints.
• Q: What does Clecomatic clutch shut-off mean?
  A: Clecomatic clutch shut-off means the tool stops driving once the preset torque is reached. This helps reduce over-tightening and makes fastening more repeatable than a direct-drive tool controlled only by operator feel.
• Q: Why choose the 1,450 RPM model instead of the 2,100 RPM version?
  A: The 1,450 RPM model provides a more moderate rundown speed for applications that need controlled fastening but do not require the fastest cycle rate. It can be a better match when the joint needs steadier seating before shut-off.
• Q: Does the 19RAA03AH3 use a 3/8" drive?
  A: Yes. This AH3 configuration uses a 3/8" square drive. Use compatible sockets that match the fastener size and the torque range of the tool.
• Q: What air setup is recommended for this nutrunner?
  A: The tool is rated at 90 PSI / 620 kPa and lists 11 SCFM air consumption. Use clean, regulated, lubricated air with a properly sized hose and FRL to support consistent torque output and reduce premature wear.
