Cleco 400PTHFC206 Shut-Off Model Pulse Tool | 2000 RPM | 3/4" Square Drive | 185 (ft-lbs) Max Torque

Built for high-torque production fastening, the Cleco 400PTHFC206 Shut-Off Model Pulse Tool gives assembly teams a 3/4" square drive, 2,000 RPM free speed, and 185 - 295 ft-lbs torque range for larger bolted joints that exceed the capacity of smaller pneumatic pulse tools. As a C Series hydraulic pulse shut-off tool, it applies torque through hydraulic pulses (short, controlled torque impulses that reduce reaction force compared with conventional impact tools) and shuts off when the preset torque is reached.

This pistol grip model is suited for production lines, fixture-based assembly, and industrial fastening stations where speed, repeatability, and reduced kickback matter. The 250 - 400 Nm torque range supports larger fasteners, while the 3/8" NPT air inlet, 1/2" hose I.D., and 33.5 SCFM air consumption make proper air supply sizing essential for consistent tool output.

Features:

• C Series pistol grip shut-off pulse tool for controlled high-torque fastening in production environments.
• Hydraulic pulse shut-off supports repeatable tightening while reducing reaction force at the operator’s hand.
• Motor governor equipped to help regulate rundown behavior during fastening cycles.
• External torque adjustment allows torque settings to be changed without internal tool disassembly.
• External speed control helps qualified users tune rundown speed to the fastener, joint, and workstation requirements.
• Reversible operation supports fastening and controlled removal tasks with the same tool.
• Oilless blades reduce internal lubrication requirements within the air motor.
• Torque signal port provides a connection point for compatible torque monitoring or production control setups.

Made in USA:

Applications:

• Heavy equipment assembly — tightening frame, bracket, suspension, and drivetrain fasteners where a 3/4" square drive is required.
• Automotive and commercial vehicle production — fastening larger chassis and subassembly bolts with reduced reaction force compared with impact-style tools.
• Rail and transportation manufacturing — controlled tightening on larger bolted assemblies used in cars, trucks, rail equipment, and fleet components.
• Industrial production lines — repeat fastening of M12 to M20 bolts where torque range, speed control, and shut-off operation are part of the assembly process.
• Plant MRO and tool crib programs — supporting maintenance teams that need a high-torque pneumatic pulse tool for larger nuts and bolts.

FAQs:

• Q: What does “shut-off model” mean on the Cleco 400PTHFC206?
  A: Shut-off means the tool is built to stop the fastening cycle when the preset torque level is reached. This helps improve repeatability compared with manually feathering the trigger or relying only on operator feel.
• Q: Is this tool the right choice for loosening stuck bolts?
  A: The 400PTHFC206 is primarily a controlled fastening pulse tool, not a breakaway impact wrench. It can reverse for removal tasks, but seized fastener removal is usually better handled by an impact wrench selected for breakaway torque.
• Q: What air supply should be used with this pulse tool?
  A: The tool lists 33.5 SCFM air consumption, a 3/8" NPT air inlet, and a 1/2" hose I.D. Use a compressor, FRL, hose, and fittings that can maintain adequate volume at the tool during production use.
• Q: What size sockets fit the 400PTHFC206?
  A: This model uses a 3/4" square drive, so it should be paired with compatible 3/4" drive impact-rated sockets. Do not use hand sockets or undersized adapters in high-torque production fastening.
• Q: How does this model compare with the 250PTHFC226?
  A: The 400PTHFC206 covers a higher torque range at 185 - 295 ft-lbs and runs at 2,000 RPM. The 250PTHFC226 is the lower-torque model in the same general C Series shut-off pulse tool family.
