Cleco 35PTHH40Q Shut-Off Model Pneumatic Pulse Tool | H-Series | 4000 RPM | 1/4" Quick Change Drive | 14.8 - 25.8 (ft-lbs) Torque Range

Built for controlled assembly work where fasteners must be tightened quickly without the harsh reaction of an impact wrench, the Cleco 35PTHH40Q H-Series shut-off pneumatic pulse tool delivers a 14.8 - 25.8 ft-lbs torque range for medium-duty fastening on production lines, repair benches, and industrial assembly stations. Its hydraulic pulse mechanism (a sealed pulse unit that transfers torque in short hydraulic impulses) helps reduce reaction force compared with conventional impact tools, while the shut-off design stops the tool at the set torque to support repeatable fastening.

With a 1/4" quick change drive, 4,000 RPM free speed, and 15.9 SCFM air consumption, the 35PTHH40Q is suited for users who need fast rundown speed, bit-style socket compatibility, and controlled torque in one compact pistol-grip tool. The H-Series platform includes external torque adjustment, external speed control, a torque signal port, and reversible operation, giving assembly teams a practical pneumatic option for fasteners in the 20 - 35 Nm range.

Type: Pneumatic Pulse Tool | Series: H-Series | Model: 35PTHH40Q | Configuration: Pistol Grip Shut-Off | Drive Type: 1/4" Quick Change | Torque Range: 14.8 - 25.8 ft-lbs / 20 - 35 Nm | Free Speed: 4,000 RPM | Weight: 2.31 lbs / 1.05 kg | Air Inlet: 1/4" NPT | Recommended Hose I.D.: 1/2" | Air Consumption: 15.9 SCFM | Rated Air Pressure: 87 PSI / 6 bar

Features:

• Inertia shut-off supports repeatable fastening by stopping the tool when the preset torque is reached.
• Motor governor equipped to help maintain controlled tool speed during assembly work.
• External torque adjustment allows torque changes without disassembling the tool.
• External speed control helps tune rundown speed for hard-joint and soft-joint fastening conditions.
• Torque signal port is included on pistol grip models for assembly-line monitoring or process feedback.
• Adjustable pulse unit volume simplifies maintenance of the hydraulic pulse mechanism.
• Market-leading repeatability supports production fastening where consistent results matter.
• Reversible operation and oilless blades support everyday assembly use and routine fastener removal.

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

Applications:

• Automotive and transportation assembly — tightening medium-size bolts, brackets, covers, and subassemblies where low reaction force and repeatability are important.
• Industrial production lines — fastening parts in repeatable station work with external torque and speed settings for process control.
• Appliance and equipment manufacturing — running down bolts and threaded fasteners in housings, frames, panels, and mechanical assemblies.
• Maintenance and repair benches — controlled fastening on fixtures, small machinery, and components that require more repeatability than a general impact wrench.
• Assembly tooling programs — standardizing pneumatic pulse tools across stations using the H-Series shut-off platform and quick change drive configuration.

FAQs:

• Q: What does a pneumatic pulse tool do?
  A: A pneumatic pulse tool tightens fasteners using a hydraulic pulse mechanism instead of a conventional impact hammer. This helps reduce torque reaction felt by the operator while still providing fast rundown speed for production fastening.
• Q: What does “shut-off” mean on the Cleco 35PTHH40Q?
  A: Shut-off means the tool stops when it reaches the preset torque. This helps improve fastening consistency compared with non shut-off tools that rely more heavily on operator timing.
• Q: What air supply does the 35PTHH40Q require?
  A: Cleco rates this tool at 15.9 SCFM with performance measured at 87 PSI / 6 bar. The air system should be sized to supply the tool at that pressure while also accounting for hose length, fittings, and any other tools running on the same line.
• Q: What bits or sockets fit the 1/4" quick change drive?
  A: The 1/4" quick change output is used with compatible quick-change bit holders and drive adapters. Confirm the adapter style and fastener interface before ordering sockets or accessories.
• Q: Is this the same as the 35PTHH403?
  A: No. The 35PTHH40Q uses a 1/4" quick change drive, while the 35PTHH403 uses a 3/8" square drive. Both models share the same 14.8 - 25.8 ft-lbs torque range and 4,000 RPM free speed, but the output drive determines which accessories fit.
