Cleco 35PTHHA403 Shut-Off Model Hydraulic Pulse Tool | H Series | Pistol Grip | 4000 RPM | 3/8" Square Drive | 14.8 - 14.8 (ft-lbs) Torque Range

Built for controlled fastening in production assembly environments, the Cleco 35PTHHA403 H Series Shut-Off Hydraulic Pulse Tool combines a 3/8" square drive, 4,000 RPM free speed, and a manufacturer-published 14.8–25.8 ft-lbs torque range for tightening M10-class fasteners where repeatability matters. Its hydraulic pulse mechanism delivers torque through short oil-cushioned pulses, helping reduce the reaction force transferred to the operator compared with conventional impact-style fastening. The shut-off function stops the rundown at the preset torque, supporting consistent assembly results across repeated cycles.

The pistol grip layout gives operators a familiar trigger-style tool for bench assembly, fixture work, and horizontal fastening tasks. As part of Cleco’s H Series 4–120 Nm shut-off pulse tool range, the 35PTHHA403 is intended for manufacturing teams that need low-reaction fastening, production repeatability, and pneumatic tool simplicity. With a 2.45 lb tool weight, 1/4" air inlet, 15.90 SCFM air consumption, and 1/2" recommended hose I.D., this model should be matched to the plant air system, FRL setup, and required joint torque before being placed into service.

Features:

• Hydraulic pulse fastening helps limit reaction force during repetitive tightening operations.
• Shut-off model stops the tool at the preset torque, supporting repeatable fastening in production environments.
• Inertia shut-off system contributes to controlled tool operation across repeated rundowns.
• Efficient 3-chamber air motor supports consistent pneumatic performance during assembly use.
• External speed control allows the tool to be adjusted for the application without changing the basic tool configuration.
• Oil-less blades reduce routine lubrication requirements inside the motor assembly.
• Reversible torque signal port supports integration with compatible assembly tooling setups where torque signal feedback is required.
• Low noise level helps make the tool suitable for multi-station production areas.

Applications:

• Automotive assembly — tightening M10 fasteners on brackets, subassemblies, interior structures, and light chassis-related components.
• Industrial manufacturing — repeatable bolt rundown in pneumatic workcells, fixture stations, and assembly benches.
• Appliance and equipment production — controlled fastening where consistent torque and reduced reaction force help maintain assembly quality.
• Aerospace and transportation assembly — repetitive fastening tasks where tool weight, reaction control, and torque range must be matched to the joint.
• MRO tool cribs — replacement or standardization tool for facilities already using Cleco H Series hydraulic pulse tools.

FAQs:

• Q: What is the torque range of the Cleco 35PTHHA403?
  A: The manufacturer-published torque range is 14.8–25.8 ft-lbs, or 20–35 Nm. Final torque should always be verified on the actual joint using your plant’s torque audit process.
• Q: What does “shut-off” mean on this Cleco pulse tool?
  A: Shut-off means the tool is intended to stop when the preset torque is reached. This helps improve fastening consistency compared with tools that rely only on operator trigger control.
• Q: What is a hydraulic pulse tool used for?
  A: Hydraulic pulse tools are used for repetitive tightening where reduced reaction force and repeatable torque are important. They are commonly used in production assembly rather than high-breakaway service work.
• Q: What socket type does this model use?
  A: The 35PTHHA403 uses a 3/8" square drive, so it accepts compatible 3/8" square-drive sockets rated for the fastening application.
• Q: Is this tool for removing rusted bolts or lug nuts?
  A: No. This model is a controlled assembly fastening tool, not a general-purpose impact wrench for breakaway torque. For removal work, choose an impact wrench matched to the required breakaway torque and socket drive size.
