Cleco 75RNL-4V-4 Pneumatic Stall Collar Reverse Angle Nutrunner | 75 Series | Lever Start | 280 RPM | 105 (ft-lbs) Max Torque

Built for higher-torque production fastening where clearance is limited, the Cleco 75RNL-4V-4 Pneumatic Stall Collar Reverse Angle Nutrunner delivers 280 RPM free speed with 105 ft-lbs maximum torque. This 75 Series lever start tool uses stall fastening (the air motor stops as joint resistance reaches the tool’s torque capability), giving operators controlled rundown without impact blows. The reverse angle configuration helps reach fasteners near frames, brackets, fixtures, and other assembly obstructions.

The 75RNL-4V-4 is suited for industrial assembly stations that require a reversible pneumatic nutrunner for tightening and backing out larger threaded fasteners. Its 280 RPM speed supports controlled fastener rundown, while the 105 ft-lbs torque capacity makes it appropriate for heavier nut and bolt applications within the manufacturer’s specified range.

Made in USA:

Applications:

• Heavy equipment assembly — tightening larger nuts and bolts around frames, brackets, and mounted components.
• Industrial manufacturing — controlled pneumatic fastening on production lines and fixture-based workstations.
• Vehicle and machinery assembly — reversible angle fastening where straight tools cannot reach comfortably.
• Plant maintenance and rework — removing and reinstalling threaded fasteners during adjustment or repair tasks.
• Fabricated structure assembly — fastening operations that require access around plates, supports, and welded assemblies.

FAQs:

• Q: What does “stall collar” mean on this Cleco nutrunner?
  A: It refers to a stall-style fastening tool that tightens until joint resistance causes the air motor to stall. This provides controlled fastening without an impact mechanism.
• Q: What is the maximum torque of the Cleco 75RNL-4V-4?
  A: The 75RNL-4V-4 has a maximum torque rating of 105 ft-lbs. Always confirm that the joint, fastener size, and torque requirement fall within the tool’s intended operating range.
• Q: Why choose an angle nutrunner for assembly work?
  A: An angle nutrunner reaches fasteners located close to fixtures, frames, housings, and other obstructions. This makes it useful when a pistol or straight inline tool does not provide adequate access.
• Q: Can this tool remove fasteners as well as tighten them?
  A: Yes. The reverse function allows the tool to back out fasteners during rework, adjustment, and maintenance operations.
