Cleco 19RAA12AH2 Pneumatic Collar Reversible Angle Nutrunner | Lever Start | 19 Series | 200 RPM | Clutch Shut-Off | 1.8 - 8.3 (ft-lbs) Torque Range

Built for controlled fastening in compact assemblies, the Cleco 19RAA12AH2 pneumatic collar reversible angle nutrunner gives operators a slower-speed, torque-focused option for small fasteners where repeatability matters. This 19 Series lever-start model runs at 200 RPM, allowing more controlled rundown than higher-speed tools when the joint requires careful seating. Its Clecomatic clutch shut-off system automatically stops the tool at the preset torque, helping reduce over-tightening on production parts, service assemblies, and low-torque bolted joints.

The 1/4" square drive accepts compatible sockets for small fasteners, while the right-angle head helps reach around brackets, housings, panels, and other obstacles where inline nutrunners may not fit. Collar reverse allows fast direction changes for backing off fasteners or correcting assemblies, and the lever start gives the operator controlled engagement during socket placement and rundown.

Features:

• Clecomatic clutch shut-off stops the tool at the selected torque to support repeatable fastening in production and assembly environments.
• 200 RPM free speed gives operators controlled rundown on low-torque fasteners where a slower, steadier approach is preferred.
• Right-angle configuration reaches fasteners located close to panels, brackets, frame members, and other assembly obstructions.
• Collar reverse allows quick clockwise and counterclockwise operation for installation, removal, adjustment, and rework.
• Lever start helps the operator position the socket before engaging the tool, reducing unwanted starts during alignment.
• 1/4" square drive fits compatible sockets used for smaller assembly fasteners.
• Grip material is tested to withstand a range of industrial chemicals found in manufacturing and maintenance 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:

• Production assembly — tightening low-torque bolts and nuts where clutch shut-off helps maintain consistent fastening results.
• Aerospace and transportation work — reaching compact joints, brackets, and internal fastening points with the right-angle head.
• Appliance and equipment manufacturing — controlled fastening on housings, sheet metal panels, frames, and component mounts.
• Automotive and light vehicle assembly — installing small brackets, trim-related hardware, and service fasteners where over-tightening must be avoided.
• Industrial maintenance and MRO — removing and reinstalling smaller fasteners during bench repair, machine adjustment, and equipment service.

FAQs:

• Q: What is the difference between the 19RAA12AH2 and faster 19 Series models?
  A: The 19RAA12AH2 runs at 200 RPM, giving operators a slower rundown speed for more controlled fastening. Faster models may reduce cycle time, but this version is better suited when joint control and careful seating are more important than maximum speed.
• Q: What does Clecomatic clutch shut-off do?
  A: The Clecomatic clutch shut-off stops the tool once the preset torque is reached. This helps improve repeatability and reduces the risk of continuing to drive the fastener after the target torque has been achieved.
• Q: Does this model use a 1/4" or 3/8" drive?
  A: The 19RAA12AH2 uses a 1/4" square drive. Buyers needing a 3/8" square drive should verify the corresponding AH3 version before ordering.
• Q: Why use a right-angle nutrunner instead of a straight nutrunner?
  A: A right-angle nutrunner reaches fasteners positioned close to side walls, brackets, housings, or frame members. It lets the socket approach the fastener from the side when a straight inline tool does not have enough clearance.
• Q: What air setup should be used with this tool?
  A: The tool is rated at 90 PSI / 620 kPa and should be supplied with clean, regulated, lubricated air. A properly sized FRL and air hose help maintain torque consistency and reduce premature tool wear.
