Cleco 11PTHH353 Shut-Off Model Pneumatic Pulse Tool | H-Series | 3,500 RPM | 3/8" Square Drive | 4.43 - 8.1 (ft-lbs) Torque Range

Built for controlled small-fastener assembly where a square drive is preferred over a quick-change bit holder, the Cleco 11PTHH353 H-Series shut-off pneumatic pulse tool delivers a 4.43 - 8.1 ft-lbs torque range with a 3/8" square drive for use with compatible sockets. It's 3,500 RPM free speed supports fast rundown before final torque, while the hydraulic pulse mechanism reduces reaction force compared with conventional impact tools, helping operators maintain control during repetitive fastening cycles.

The 11PTHH353 is a shut-off pulse tool, meaning the tool stops when the preset torque is reached to help improve fastening repeatability and reduce over-tightening. With 7.06 SCFM air consumption, a 1/4" NPT air inlet, and a recommended 3/8" hose I.D., this pistol-grip Cleco pulse tool is suited for assembly stations, component installation, and maintenance work where controlled torque and socket compatibility matter.

Type: Shut-Off Pneumatic Pulse Tool | Series: H-Series | Model: 11PTHH353 | Drive Size: 3/8" | Drive Type: Square Drive | Torque Range: 4.43 - 8.1 ft-lbs | Torque Range: 6 - 11 Nm | Free Speed: 3,500 RPM | Weight: 1.83 lbs | Air Consumption: 7.06 SCFM | Air Inlet: 1/4" NPT | Recommended Hose I.D.: 3/8"

Features:

• Shut-off model stops at the preset torque to support repeatable fastening in production and assembly environments.
• Hydraulic pulse mechanism delivers low-reaction fastening, helping reduce the kickback associated with traditional impact tools.
• 3/8" square drive accepts compatible sockets for small bolts, nuts, and assembly fasteners.
• 3,500 RPM free speed helps reduce rundown time before the tool reaches final torque.
• Efficient 3-chamber air motor supports consistent fastening performance with 7.06 SCFM air consumption.
• External speed control allows rundown behavior to be adjusted without opening the tool.
• Low noise level supports assembly areas where communication and repeated tool use are part of the workday.
• Compact pistol-grip body helps operators handle horizontal, vertical, and fixture-based fastening positions.

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

Applications:

• Industrial assembly stations: Controlled fastening of small bolts and nuts where a 3/8" socket drive is required.
• Automotive component assembly: Installing brackets, light hardware, interior components, and subassemblies within the 4.43 - 8.1 ft-lbs torque range.
• Appliance and equipment manufacturing: Repetitive socket-based fastening on housings, frames, panels, guards, and small mechanical assemblies.
• Bench and fixture work: Low-reaction fastening where operators complete frequent cycles at the same workstation.
• Maintenance and repair departments: Controlled reassembly of light covers, guards, brackets, and service components where an impact wrench would be too aggressive.

FAQs:

• Q: What is the Cleco 11PTHH353 used for?
  A: The 11PTHH353 is used for controlled low-torque fastening with sockets. It is intended for assembly and production work where repeatable torque and low reaction force are more important than high breakaway power.
• Q: What is the difference between the 11PTHH353 and the 11PTHH35Q?
  A: The 11PTHH353 uses a 3/8" square drive for sockets, while the 11PTHH35Q uses a 1/4" quick change drive for hex bits. Both models share the same 4.43 - 8.1 ft-lbs torque range and 3,500 RPM free speed.
• Q: What does shut-off mean on this Cleco pulse tool?
  A: Shut-off means the tool stops automatically when the preset torque is reached. This helps reduce over-tightening and supports more consistent results across repeated fastening cycles.
• Q: Can this tool remove lug nuts or seized fasteners?
  A: No. This model is a low-torque assembly tool with a 4.43 - 8.1 ft-lbs torque range. Lug nuts, corroded bolts, and high-torque service work require a properly sized impact wrench or higher-torque nutrunner.
• Q: What air setup should be used with the 11PTHH353?
  A: Use clean, regulated compressed air through a properly sized air line. This model lists 7.06 SCFM air consumption, a 1/4" NPT air inlet, and a recommended 3/8" hose I.D.
