Cleco 34RAA75AZ4 Clutch Shut-Off Pneumatic Angle Nutrunner | Lever Start | 155 RPM | 28 - 55 (ft-lbs) Torque Range | 1/2" Drive

Built for controlled fastening in assembly stations, machinery build-out, and service environments, the Cleco 34RAA75AZ4 clutch shut-off pneumatic angle nutrunner combines a 28 - 55 ft-lbs torque range with a 1/2" square drive for tightening larger socket-driven fasteners with repeatable results. The clutch shut-off system automatically stops the tool when the preset torque is reached, helping reduce over-tightening on production and repair work. It's 155 RPM free speed supports steady run-down without rushing the final torque event, while the angle head helps reach fasteners positioned near housings, brackets, frames, and other obstructions.

Part of Cleco’s 34 Series, this lever-start angle nutrunner uses the Clecomatic Clutch, a torque-control clutch system built for repeatable fastening and longer calibration intervals. The lever start gives the operator controlled engagement at the fastener, and the collar reverse allows direction changes without moving to a separate control. With a 17" overall length, 1.60" head height, and 0.70" side-to-center distance, the 34RAA75AZ4 is suited for assembly areas where torque accuracy and access both matter.

Features:

• Clutch shut-off operation stops the tool when the preset torque is reached, helping support consistent fastening on controlled assembly work.
• Clecomatic Clutch delivers strong torque repeatability and a long calibration cycle for production fastening environments.
• Indexable angle head improves access around brackets, housings, frames, and other tight assembly locations.
• Lever start allows controlled tool engagement at the fastener for more deliberate starts during repetitive fastening.
• Collar reverse lets operators change fastening direction without shifting to a separate reverse control.
• Heavy-duty Cleco motor is the industry standard for reliability in pneumatic assembly tools.
• Oil-less blades reduce oil mist in the work area compared with conventional lubricated blade designs.
• Lightweight, ergonomic, and easy-to-service construction supports daily use in assembly and maintenance settings.

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

Applications:

• Automotive and off-highway assembly — tightening bracket, frame, suspension, and powertrain fasteners where controlled torque is required.
• Heavy truck and trailer production — fastening larger socket-driven hardware in positions where a straight tool may not provide enough access.
• Industrial machinery assembly — running down and final-tightening fasteners on equipment frames, guards, mounts, and subassemblies.
• Agriculture and lawn equipment manufacturing — repeatable tightening on machinery builds that require medium-to-high torque in compact areas.
• Plant maintenance and MRO — controlled tightening during equipment repair, fixture setup, and component replacement where torque consistency matters.

FAQs:

• Q: What does clutch shut-off mean on this Cleco angle nutrunner?
  A: Clutch shut-off means the tool stops automatically when the preset torque is reached. This helps reduce over-tightening and supports more repeatable fastening than manual throttle control alone.
• Q: What type of sockets fit the 34RAA75AZ4?
  A: This model uses a 1/2" square drive, so it is intended for compatible 1/2" drive sockets and tooling. Always match the socket to the fastener size, torque requirement, and the operating environment.
• Q: Why choose an angle nutrunner instead of a straight nutrunner?
  A: The angle head helps reach fasteners located close to housings, brackets, frames, and other obstructions. It is useful when the fastener axis is not easily reached with an inline or pistol-style tool.
• Q: Is this tool for precision assembly or general impact fastening?
  A: The 34RAA75AZ4 is a clutch shut-off assembly nutrunner, not an impact wrench. It is used where controlled torque and repeatability are more important than breakaway impact force.
• Q: Does this tool require an FRL?
  A: For best pneumatic tool performance, use clean, regulated air and follow the manufacturer’s lubrication and air preparation requirements. A properly sized Filter-Regulator-Lubricator helps protect the tool and maintain consistent operation.
