Cleco 19RAA11AH3 Pneumatic Collar Reversible Angle Nutrunner | Lever Start | 19 Series | 340 RPM | Clutch Shut-Off | 1.8 - 8.3 (ft-lbs) Torque Range

When your assembly process needs controlled torque in a confined fastening area, the Cleco 19RAA11AH3 pneumatic collar reversible angle nutrunner delivers repeatable shut-off performance in a compact right-angle format. Its 3/8" square drive fits common production sockets, while the 340 RPM free speed supports steady rundown on threaded fasteners without turning the tool into a high-speed, hard-to-control driver. The CLECOmatic clutch shut-off system stops the tool once the preset torque is reached, helping reduce over-tightening on repeat assembly work.

Part of Cleco’s 19 Series, this lever-start angle nutrunner is built for light- to medium-torque production fastening where access, repeatability, and tool control matter more than breakaway force. The 1.8 - 8.3 ft-lbs torque range suits small fasteners, brackets, covers, subassemblies, and other controlled assembly jobs, while the collar reverse lets operators change direction at the tool for removal or rework.

Features:

• CLECOmatic clutch shut-off stops the tool when the preset torque is reached, supporting consistent fastening from part to part.
• Right-angle head reaches fasteners where a pistol or inline tool may not fit, including brackets, housings, and recessed assembly points.
• Collar reverse allows direction changes at the tool for backing out fasteners during adjustment, rework, or disassembly.
• Lever start gives operators controlled actuation during repetitive production fastening cycles.
• 3/8" square drive supports socket-based assembly work without requiring specialty hex bits.
• 340 RPM free speed balances controlled rundown with practical cycle time on small fasteners.
• Compact 0.50" side-to-center distance helps position the socket close to nearby walls, ribs, or fixture edges.

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 small nuts and bolts where repeatable shut-off torque is required.
• Automotive and transportation subassemblies — fastening brackets, covers, panels, and light mechanical components.
• Appliance and equipment manufacturing — controlled assembly work on frames, housings, guards, and access panels.
• Industrial MRO and rework stations — removing and reinstalling fasteners during service, inspection, and repair.
• Fixture-based assembly cells — reaching fasteners near tooling, clamps, and other access-limiting obstructions.

FAQs:

• Q: What does CLECOmatic clutch shut-off mean?
  A: CLECOmatic clutch shut-off means the tool automatically stops when the clutch reaches the preset torque. This helps improve repeatability compared with a non-shut-off tool that depends more heavily on operator feel.
• Q: Is the 19RAA11AH3 a good choice for tight spaces?
  A: Yes. The angle-head configuration and 0.50" side-to-center distance help the socket reach fasteners close to walls, fixtures, or adjacent parts.
• Q: What sockets fit this model?
  A: This model uses a 3/8" square drive, so it accepts compatible 3/8" drive sockets that match the fastener size and application requirements.
• Q: What is the difference between the full tool torque range and the standard spring range?
  A: The tool range is 18 - 100 in-lbs / 2.0 - 11.3 Nm, while the standard spring range is 30 - 100 in-lbs / 3.4 - 11.3 Nm. Use the standard spring range when setting torque with the factory spring configuration.
• Q: Is this tool for loosening seized fasteners?
  A: No. This is a controlled assembly nutrunner, not an impact wrench. It is intended for repeatable fastening and light removal or rework within its torque range.
