Cleco 34RAA37AX3 Clutch Shut-Off Pneumatic Angle Nutrunner | Lever Start | 480 RPM | 14 - 27 (ft-lbs) Torque Range | 3/8" Drive

For controlled fastening in compact assembly areas, the Cleco 34RAA37AX3 Clutch Shut-Off Pneumatic Angle Nutrunner combines right-angle access with repeatable torque shut-off for production and maintenance work. Its 14 - 27 ft-lbs torque range gives assembly teams a slightly higher torque band than lower-output 34 Series models, while the 480 RPM free speed supports steady rundown on medium-torque bolts without making the tool difficult to control. The 3/8" square drive accepts compatible sockets for fastening brackets, housings, fixtures, and machinery components where a straight nutrunner cannot reach the fastener cleanly.

The 34RAA37AX3 uses Cleco’s Clecomatic Clutch, a shut-off clutch system that stops the tool when the preset torque is reached to help reduce over-tightening and improve joint consistency. Its lever start gives the operator deliberate activation, the collar reverse allows quick direction changes, and the indexable angle head helps position the drive around obstructions, flanges, panels, and fixtured assemblies.

Features:

• Clecomatic Clutch shut-off system helps stop the tool at the preset torque for repeatable assembly fastening.
• 14 - 27 ft-lbs torque range supports medium-torque bolting tasks on production fixtures, equipment assemblies, and service components.
• 480 RPM free speed provides controlled rundown speed for fasteners that require torque consistency rather than impact force.
• 3/8" square drive fits compatible sockets commonly used in assembly and industrial maintenance applications.
• Angle head configuration reaches fasteners near corners, brackets, housings, and other restricted-access areas.
• Indexable angle head allows the head position to be adjusted for different fastening approaches and workstation layouts.
• Lever start supports deliberate activation during repetitive fastening operations.
• Collar reverse helps operators back off fasteners, correct alignment, or perform rework without changing tools.

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

Applications:

• Industrial assembly — controlled tightening of medium-torque fasteners on machinery, equipment frames, and production subassemblies.
• Automotive and off-road equipment production — fastening brackets, covers, housings, and structural components where angle access is required.
• Plant maintenance and MRO — removing and reinstalling fasteners during equipment repair, fixture adjustment, and component replacement.
• Rail, appliance, and general manufacturing — repeatable torque-controlled fastening in work cells, benches, and assembly stations.
• Fixture and jig work — driving fasteners close to walls, flanges, or adjacent parts where a pistol or inline tool may not fit.

FAQs:

• Q: What is the benefit of a shut-off clutch on the 34RAA37AX3?
  A: The shut-off clutch stops the nutrunner once the preset torque is reached. This helps improve fastening repeatability and reduces the chance of continuing to drive the fastener after the target torque has been achieved.
• Q: Is this Cleco angle nutrunner the same as an impact wrench?
  A: No. This is a controlled-torque assembly nutrunner, not an impact tool for breaking loose seized fasteners. It is best used within its 14 - 27 ft-lbs torque range for assembly and maintenance fastening.
• Q: What does the 0.67" side-to-center dimension tell me?
  A: Side-to-center distance helps determine whether the angle head can reach a fastener near a wall, flange, bracket, or adjacent component. A smaller side-to-center distance improves access in tight fastening locations.
• Q: What air supply does this model require?
  A: Manufacturer data lists a 3/8" NPT air inlet, 5/16" minimum hose I.D., and 34 SCFM air consumption. Use a properly sized compressed air system and maintain correct operating pressure for consistent torque performance.
• Q: Does the 34RAA37AX3 include sockets?
  A: Sockets are not listed in the provided standard equipment data. Select compatible 3/8" drive sockets separately based on fastener size and application requirements.
