Cleco 34RAS28AH3 Pneumatic Stall Collar Reverse Angle Nutrunner | 34 Series | Lever Start | 710 RPM | 20 (ft-lbs) Max Torque

For assembly jobs that need more torque than light-angle tools but still require tight access, the Cleco 34RAS28AH3 pneumatic stall collar reverse-angle nutrunner delivers controlled fastening in a compact right-angle format. This 34 Series reversible stall nutrunner provides 20 ft-lbs / 28 Nm maximum torque, giving production teams useful fastening capacity for bracket work, mechanical subassemblies, and smaller bolted joints where a straight tool or impact wrench is not the right fit. Its 710 RPM free speed supports steady run-down on repeated fastening cycles, while the 3/8" square drive accepts compatible sockets for common assembly hardware.

The 34RAS28AH3 uses stall torque control, which means the tool’s output is controlled through air pressure, and the tool stalls as the fastener reaches the available torque. This makes it important to pair the nutrunner with accurate air regulation, especially when repeatable fastening results matter. The right-angle head helps place the socket close to panels, flanges, fixture edges, and other obstructions, and the 0.6" / 14 mm side-to-center distance gives operators better access to fasteners located near adjacent surfaces. The AH configuration identifies a heavy duty angle head in Cleco’s model structure, making this model a practical choice for higher-torque assembly work within the 34 Series stall range.

Features:

• Reversible right-angle configuration supports both fastener installation and removal in assembly areas where inline nutrunners may not clear the workpiece.
• Stall torque control allows torque output to be adjusted through air pressure regulation for straightforward production fastening setups.
• AH heavy duty angle head configuration provides a higher-torque angle head option within the 34 Series reversible stall tool lineup.
• Lever start gives the operator controlled activation during socket placement, run-down, and final seating.
• Collar reverse keeps the reversing control at the tool body for quick direction changes during repetitive assembly and rework tasks.
• 3/8" square drive works with compatible sockets used for nuts, bolts, and production fastening hardware.
• Compact 0.6" side-to-center dimension helps the operator reach fasteners positioned close to walls, housings, or fixture components.
• Standard equipment includes operating instructions and service manual.

Made in USA:

Applications:

• Mechanical assembly stations — fastening brackets, covers, plates, and subassemblies with 3/8" drive sockets.
• Automotive and transportation component assembly — running smaller bolts and nuts in areas with restricted tool clearance.
• Appliance, machinery, and equipment production — tightening hardware around housings, frames, and fixture-mounted workpieces.
• Industrial MRO benches — removing and reinstalling compatible fasteners during service, inspection, and rebuild work.
• Fixture-based fastening cells — reaching fasteners located near clamps, locating pins, guards, or surrounding tooling.

FAQs:

• Q: What does the 20 ft-lbs maximum torque rating mean?
  A: The 20 ft-lbs / 28 Nm rating is the maximum torque capacity listed for this model. It should be matched to the fastener size, joint type, and required assembly torque before use.
• Q: How is a stall nutrunner different from a shut-off clutch nutrunner?
  A: A stall nutrunner does not automatically shut off at a preset torque. Instead, torque is controlled through air pressure, and the tool stalls when the joint load reaches the available output torque.
• Q: What air setup is recommended for this tool?
  A: Cleco rates this model at 90 psi / 620 kPa and lists 34 SCFM air consumption. Use a properly sized air supply with a regulator so the tool can deliver the intended torque output.
• Q: Can this model be used for removing fasteners?
  A: Yes. The 34RAS28AH3 is reversible and uses collar reverse, so it can be used for both installation and removal when the fastener torque is within the tool’s capability.
• Q: Is this tool meant for impact-style breakaway work?
  A: No. This is a pneumatic angle nutrunner for controlled fastening, not an impact wrench. For stuck, rusted, or high-breakaway fasteners, choose a properly rated impact tool instead.
