Cleco 34RAA75AZ3 Clutch Shut-Off Pneumatic Angle Nutrunner | Lever Start | 155 RPM | 28 - 55 (ft-lbs) Torque Range | 3/8" Drive

When a fastening station calls for controlled torque in a tight envelope, the Cleco 34RAA75AZ3 clutch shut-off pneumatic angle nutrunner provides a practical combination of access, repeatability, and power. This 34 Series tool delivers a 28 - 55 ft-lbs torque range for medium-torque assembly work, while the 3/8" square drive accepts compatible industrial sockets for bolts, nuts, and threaded fasteners used across production and maintenance environments.

The Clecomatic clutch shut-off system stops the tool at the preset torque, helping reduce under-tightening and over-tightening on repetitive fastening jobs. Its 155 RPM free speed is suited for controlled rundown where accuracy matters more than high-speed cycling, and the lever start gives the operator deliberate engagement at the fastener. With a right-angle head, 17.0" overall length, and 0.70" side-to-center distance, the 34RAA75AZ3 helps reach fasteners near housings, brackets, rails, and fixtures where straight nutrunners may not fit cleanly.

• Indexable angle head allows the head position to be adjusted for improved alignment in changing assembly layouts.
• Lever start supports controlled engagement when seating the socket on the fastener.
• Collar reverse lets the operator quickly switch direction for fastener removal, correction, or rework.
• Oil-less blades help reduce oil mist in the work area while supporting normal pneumatic tool operation.

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

Applications:

• Machinery assembly: Installing medium-torque bolts on frames, housings, mounting plates, and mechanical subassemblies.
• Automotive and truck production: Controlled fastening in areas where panels, brackets, or fixture tooling limit straight-line access.
• Industrial maintenance and MRO: Removing and reinstalling fasteners during equipment repair, line changeovers, and component replacement.
• Agricultural and construction equipment manufacturing: Tightening structural and mechanical fasteners on guards, supports, brackets, and assemblies.
• Fixture-based workstations: Repetitive socket fastening where torque shut-off and tool positioning help maintain assembly consistency.

FAQs:

• Q: What is the torque range of the Cleco 34RAA75AZ3?
  A: The 34RAA75AZ3 has a torque range of 28 - 55 ft-lbs, or 38 - 75 Nm. It should be selected only when the target fastening torque falls within that range.
• Q: Why use a clutch shut-off nutrunner instead of an impact wrench?
  A: A clutch shut-off nutrunner is used when repeatable tightening torque is more important than breakaway power. An impact wrench is better for loosening stuck fasteners, while this tool is built for controlled assembly fastening.
• Q: What does side-to-center distance mean?
  A: Side-to-center distance is the measurement from the outside edge of the angle head to the centerline of the drive. The 0.70" side-to-center distance helps buyers judge whether the head can reach fasteners near walls, brackets, or fixture edges.
• Q: What sockets fit this model?
  A: This model uses a 3/8" square drive, so it accepts compatible 3/8" drive sockets. Socket size should be matched to the fastener, torque requirement, and production standard used at the workstation.
• Q: What air setup should be used with this nutrunner?
  A: The published air consumption is 34 SCFM, with a 3/8" NPT air inlet and 5/16" minimum hose I.D. Use clean, regulated air at the manufacturer-specified pressure and pair the tool with a properly sized FRL.
