Cleco 80PTHH354 Shut-Off Model Pneumatic Pulse Tool | H-Series | 3,500 RPM | 1/2" Square Drive | 36.9 - 59 (ft-lbs) Torque Range

Built for controlled assembly fastening where repeatability matters, the Cleco 80PTHH354 H-Series shut-off pneumatic pulse tool delivers a 36.9 - 59 ft-lbs torque range for medium-torque production joints, fixture work, and general industrial bolt-up. It's 1/2" square drive accepts compatible impact-rated sockets, while the 3,500 RPM free speed helps run fasteners down quickly before final torque is reached.

The shut-off system stops the tool when the preset torque is achieved, helping reduce over-tightening and improve fastening consistency. As a pulse tool, the 80PTHH354 uses controlled pulsing action to reduce torque reaction compared with conventional impact-style fastening, making it a strong fit for automotive assembly, appliance manufacturing, heavy truck production, and MRO workstations where operators repeat the same fastening process throughout the shift.

Type: Shut-Off Pneumatic Pulse Tool | Series: H-Series | Model: 80PTHH354 | Drive Size: 1/2" | Drive Type: Square | Torque Range: 36.9 - 59 ft-lbs / 50 - 80 Nm | Free Speed: 3,500 RPM | Air Consumption: 19.40 SCFM | Air Inlet: 1/4" NPT | Recommended Hose I.D.: 3/8"

Features:

• Shut-off pulse fastening helps stop the tool at the set torque for more consistent assembly results.
• Market-leading repeatability and accuracy support production environments where fasteners must be tightened the same way from cycle to cycle.
• Inertia shut-off system provides automatic torque control without requiring the operator to manually judge final tightening.
• Efficient 3-chamber air motor supports fast rundown and steady pneumatic performance.
• External speed control allows adjustment without opening the tool housing.
• Low noise level helps reduce sound exposure in production cells and assembly stations.
• Oil-less blades and reversible torque signal port support integration into controlled fastening processes.
• Lightweight pistol grip format helps improve handling during repeated fastening tasks.

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

Applications:

• Automotive assembly — tightening brackets, subassemblies, and medium-torque fasteners where repeatability is required.
• Heavy truck and trailer production — controlled fastening on chassis, body, and equipment mounting points within the tool’s torque range.
• Appliance and equipment manufacturing — repeated fastening of housings, frames, and structural components.
• Industrial MRO workstations — socket-driven bolt-up and repair tasks where a shut-off pulse tool is preferred over a standard impact wrench.
• Agriculture and off-road equipment assembly — fastening panels, guards, supports, and machine subassemblies in production or service environments.

FAQs:

• Q: What does the shut-off feature do?
  A: The shut-off mechanism stops the tool when the preset torque is reached. This helps reduce over-tightening and supports more consistent fastening across repeated assembly cycles.
• Q: What socket style does the Cleco 80PTHH354 use?
  A: This model uses a 1/2" square drive. Use compatible 1/2" drive impact-rated sockets matched to the fastener size and application.
• Q: Is this the right tool for removing stuck bolts?
  A: No. This is a controlled assembly pulse tool, not a breakaway impact wrench. It is intended for tightening within its 36.9 - 59 ft-lbs torque range.
• Q: What air setup is recommended?
  A: The tool lists 19.40 SCFM air consumption, a 1/4" NPT air inlet, and a recommended 3/8" hose I.D. Use clean, regulated air and a properly sized FRL to support consistent performance.
• Q: What is a pulse tool?
  A: A pulse tool delivers torque through controlled pulses instead of continuous hard reaction. This helps reduce torque reaction felt by the operator while maintaining productive fastening speed.
