Cleco 75RNL-2X-6 Pneumatic Stall Collar Reverse Angle Nutrunner | 75 Series | Lever Start | 90 RPM | 325 (ft-lbs) Max Torque

When a high-torque fastener sits inside a frame, bracket, or fixture where a straight tool cannot line up, the Cleco 75RNL-2X-6 pneumatic stall collar reverse angle nutrunner provides controlled right-angle fastening for larger assembly work. This 75 Series lever-start model uses stall torque control, meaning the air motor runs until joint resistance causes the tool to stall, giving operators torque control through air pressure adjustment. With a 3/4" square drive, 90 RPM free speed, and 325 ft-lbs / 440 Nm maximum torque, it is built for slow, powerful rundown on large bolts used in heavy truck, trailer, agricultural equipment, and industrial machinery assembly.

The collar reverse design allows the operator to change direction when removing fasteners or backing off during setup, while the right-angle head helps reach recessed or obstructed fastening points. For higher-torque fastening, the 75 Series includes a torque reaction mounting plate to help manage the force created when the tool reaches stall. Tool performance data is measured at 6.2 bar inlet air pressure at the air inlet tube, so proper air supply setup is important for repeatable results.

Features:

• Stall torque control allows torque output to be adjusted by changing air pressure, making the tool useful for applications with varying torque rates.
• Right-angle head helps operators access fasteners located near frames, brackets, housings, and other assembly obstructions.
• Lever start supports controlled tool activation during fastener alignment, rundown, and removal.
• Collar reverse lets the operator switch direction when loosening fasteners or backing out during setup.
• Heavy duty motor, gearing, and angle head construction support high-torque fastening work in production and maintenance settings.
• Planetary gearing supports tool speed changes with fewer service and replacement parts.
• Heavy duty spindle bearings and splined retractable spindles help reduce friction and support torque repeatability.
• Torque reaction mounting plate is supplied with 75 Series tools to help manage reaction force during high-torque operation.

Made in USA:

Applications:

• Heavy truck and trailer assembly — tightening chassis, suspension, frame, and bracket fasteners where 3/4" square drive tooling is required.
• Agricultural and construction equipment production — running down large bolts on machinery frames, housings, and mounted components.
• Industrial machinery assembly — fastening pump bases, guards, structural supports, and fixture-mounted components in production cells.
• Plant maintenance and MRO — removing and reinstalling larger fasteners around conveyors, presses, fixtures, and equipment frames.
• Fixture-based fastening stations — reaching recessed fasteners where a pistol or inline nutrunner cannot align squarely with the joint.

FAQs:

• Q: What does “stall” mean on this Cleco nutrunner?
  A: Stall means the tool runs until fastener resistance stops the air motor. Torque is controlled by air pressure, so the tool should be set up and verified against the required joint torque before production use.
• Q: Is the 325 ft-lbs rating the tightening torque?
  A: The 325 ft-lbs / 440 Nm value is the listed maximum torque for this model. Confirm your required torque range and joint type before selecting the tool for a specific assembly process.
• Q: Why choose the 75RNL-2X-6 over the faster 75RNL-3X-6?
  A: The 75RNL-2X-6 runs slower at 90 RPM but provides higher maximum torque at 325 ft-lbs. The 75RNL-3X-6 runs faster at 120 RPM but has a lower maximum torque rating, so selection depends on whether the application needs more speed or more torque.
• Q: Does this tool require reaction control?
  A: Yes, reaction force should be managed carefully at this torque level. Cleco lists a torque reaction mounting plate as standard equipment for 75 Series tools.
• Q: What air supply does this nutrunner need?
  A: This model uses a 1/2" NPT air inlet, 1/2" minimum hose I.D., and 70 SCFM air consumption. A properly sized air line and FRL help maintain stable inlet pressure for consistent tool performance.
