When repeatable torque control matters more than raw fastening speed, the Cleco 19RAA11AH2 pneumatic collar reversible angle nutrunner gives assembly teams a compact right-angle solution for controlled rundown work. This 19 Series tool pairs a 1/4" square drive with a 1.8 - 8.3 ft-lbs torque range, giving operators the control needed for small-to-medium fasteners without stepping up to a larger, higher-reaction tool. Its 340 RPM free speed helps balance cycle time with torque accuracy, while the angle head reaches into assemblies where straight inline tools cannot maintain access.
The clutch shut-off system automatically stops the tool at the preset torque, helping reduce over-tightening and improving fastening repeatability across production runs. Collar reverse allows quick direction changes for backing off fasteners, while lever start gives the operator controlled actuation during positioning and rundown.

Features:
- Clecomatic clutch shut-off helps stop the tool at the selected torque for repeatable fastening on production assemblies.
- Right-angle head provides access around housings, brackets, panels, and other obstructions where inline nutrunners may not fit.
- Collar reverse lets operators quickly switch direction for fastener removal, correction, or rework steps.
- Lever start supports controlled tool engagement, helping the operator position the socket before beginning the rundown.
- 1/4" square drive fits compatible sockets for small fasteners commonly used in assembly and light industrial fastening.
- Grip material is tested to withstand a range of industrial chemicals, supporting use in production 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:
- Assembly line fastening — tightening small bolts, nuts, and machine screws where repeatable torque shut-off is required.
- Aerospace and transportation assembly — accessing compact joints, brackets, and subassemblies with the right-angle head.
- Appliance and equipment manufacturing — controlled fastening on housings, panels, frames, and component mounts.
- Industrial maintenance and MRO — removing and reinstalling low-torque fasteners during repair, adjustment, and service work.
- Automotive and light vehicle production — fastening interior, accessory, and small bracket hardware where torque consistency matters.
FAQs:
- Q: What does clutch shut-off mean on this Cleco nutrunner?
A: Clutch shut-off means the tool automatically stops once the preset torque is reached. This helps reduce over-tightening and supports more consistent results than a direct-drive tool controlled only by operator feel. - Q: What size drive does the 19RAA11AH2 use?
A: The 19RAA11AH2 uses a 1/4" square drive. Use compatible 1/4" drive sockets that match the fastener size and application requirements. - Q: Is this tool reversible?
A: Yes. This model uses collar reverse, allowing the operator to change direction for backing off fasteners, rework, and removal tasks. - Q: What air supply should be used with this tool?
A: Tool performance is rated at 90 PSI / 620 kPa. The manufacturer-listed air consumption is 11 SCFM, with a 1/8" air inlet and 1/4" minimum hose I.D. - Q: Where does an angle nutrunner fit better than an inline nutrunner?
A: An angle nutrunner is useful when the fastener is tucked behind a panel, inside a frame, or close to another component. The 90-degree head lets the socket approach the fastener from the side instead of requiring a straight-on path.
