Cleco 20PTHH40Q Shut-Off Model Pneumatic Pulse Tool | H-Series | 4,000 RPM | 1/4" Quick Change Drive | 7.4 - 14.8 (ft-lbs) Torque Range

Built for controlled threaded fastening in production assembly, the Cleco 20PTHH40Q H-Series Shut-Off Model Pneumatic Pulse Tool combines a 7.4 - 14.8 ft-lbs torque range with 4,000 RPM free speed for fast rundown on smaller bolts, screws, and assembly fasteners. It's 1/4" quick change drive that supports rapid bit changes during repeat fastening work, while the shut-off mechanism helps stop the tool at the set torque point for more repeatable results than a non-shut-off impact-style tool.

The H-Series pulse design uses a hydraulic pulse mechanism, which delivers torque in short pulses to reduce reaction force felt by the operator compared with many direct-drive fastening tools. With an efficient 3-chamber air motor, external speed control, and a reversible torque signal port, this Cleco pulse tool is suited for assembly stations where speed, repeatability, and lower reaction are important to the fastening process.

• Hydraulic pulse mechanism helps reduce reaction force transferred to the operator during rundown.
• 1/4" quick change drive allows fast bit changes for assembly cells using multiple fastener styles.
• 4,000 RPM free speed helps shorten fastening cycle times on appropriately sized joints.
• Efficient 3-chamber air motor supports consistent pneumatic fastening performance.
• External speed control lets technicians tune tool speed to the application and joint condition.
• Oil less blades help reduce routine maintenance requirements compared with conventional lubricated blade designs.
• Reversible torque signal port supports integration into monitored fastening processes where applicable.

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

Applications:

• Automotive assembly: Fastening brackets, covers, interior components, and light-to-medium threaded joints where repeatability matters.
• Appliance manufacturing: Installing screws and bolts on housings, frames, panels, and subassemblies at production workstations.
• Heavy truck and trailer assembly: Running down smaller assembly fasteners where a lower-reaction pulse tool is preferred over a conventional impact tool.
• Industrial production lines: Supporting repetitive fastening tasks where 1/4" quick change tooling improves bit-change speed.
• Maintenance and repair stations: Controlled fastening on fixtures, guards, access panels, and light equipment assemblies when the torque range matches the joint requirement.

FAQs:

• Q: What does a shut-off pulse tool do?
  A: A shut-off pulse tool runs the fastener down and then shuts off when the preset torque point is reached. This helps improve repeatability compared with tools that rely only on operator feel.
• Q: What does hydraulic pulse mean?
  A: Hydraulic pulse refers to a fastening mechanism that applies torque in short pulses. This helps reduce the reaction force felt in the operator’s hand and wrist during repetitive fastening.
• Q: What bits fit the 20PTHH40Q?
  A: This model uses a 1/4" quick change drive. Use compatible 1/4" hex quick change bits, extensions, or adapters that match the fastener and application requirements.
• Q: Is the 7.4 - 14.8 ft-lbs torque range suitable for large bolts?
  A: No. This tool is intended for controlled assembly fastening within its stated torque range. For larger bolts or higher breakaway torque, choose a higher-torque Cleco pulse tool, nutrunner, or impact wrench.
• Q: Does this tool require an FRL?
  A: Pneumatic assembly tools should be used with clean, regulated air. A properly sized Filter-Regulator-Lubricator helps protect the tool and keeps air pressure consistent at the workstation.
