Cleco 70ESN4000UA12MT NeoTek Inline Corded Electric Nutrunner | 18 RPM | 922 - 2950 (ft-lbs) Torque Range | 11/2" Square Drive

When high-torque assembly work requires controlled fastening instead of impact-style tightening, the Cleco 70ESN4000UA12MT NeoTek Inline Corded Electric Nutrunner delivers a 922 to 2950 ft-lbs torque range for large bolted joints, structural assemblies, and production fastening stations. Its 18 RPM free speed provides deliberate rundown control at the top end of the 70 Series torque range, while the 1-1/2" square drive connects to large industrial sockets used on heavy machinery, rail, energy, and transportation equipment. As a transducer-control tool, it measures torque through an internal sensor for controlled tightening where process repeatability matters.

Part of Cleco’s NeoTek 70 Series high-torque corded electric platform, the 70ESN4000UA12MT supports data-driven fastening with on-board tool memory, configurable operator feedback, and preventive maintenance monitoring. The inline body format helps keep the tool aligned with the fastener axis, making it suitable for fixtured work, reaction-arm setups, and controlled assembly processes where torque output, documentation, and repeatable fastening strategy are more important than breakaway impact force.

Features:

• Transducer-control fastening helps support torque monitoring and repeatable tightening on safety-critical or quality-controlled joints.
• High-torque NeoTek 70 Series platform covers fastening applications up to 4000 Nm, making this model suitable for very large threaded assemblies.
• Configurable LED light rings provide visual operator feedback during fastening sequences and tool status checks.
• Data logging with on-board tool memory records tool activity for process review and maintenance planning.
• Preventive maintenance alerts help maintenance teams schedule service before avoidable downtime interrupts production.
• Internal temperature monitoring helps protect the tool during repeated high-torque cycles.
• Configurable multi-function buttons allow the tool interface to be adapted to the fastening process or operator workflow.
• Quarter-turn tool cable connection supports fast cable connection and service access in production environments.

Applications:

• Heavy equipment assembly: Tightening large bolted joints on frames, driveline components, hydraulic structures, and machinery assemblies requiring controlled torque.
• Rail and transportation manufacturing: Applying repeatable torque to large fasteners used in bogies, couplers, suspension components, and vehicle structures.
• Energy and infrastructure equipment: Controlled fastening on wind, power generation, oil and gas, and utility equipment where torque traceability may be required.
• Industrial production lines: Use with reaction arms, fixtures, or controlled workstations for repetitive high-torque fastening processes.
• Plant maintenance and rebuild operations: Assembly work on presses, gearboxes, pumps, and large machinery where documented tightening is preferred over impact tightening.

FAQs:

• Q: Is the Cleco 70ESN4000UA12MT an impact wrench?
  A: No. This is a corded electric nutrunner, not an impact wrench. It is used for controlled torque tightening, while an impact wrench is typically used for faster rundown and breakaway removal work.
• Q: What does transducer control mean on this nutrunner?
  A: Transducer control means the tool uses an internal torque sensor to monitor the tightening process. This helps support repeatability and process control in production fastening applications.
• Q: What socket drive does this model use?
  A: The 70ESN4000UA12MT uses a 1-1/2" square drive, so sockets and accessories must match that drive size and be rated for the torque being applied.
• Q: Does this tool require a controller?
  A: Yes. NeoTek corded electric nutrunners operate as part of a controlled fastening system and require a compatible controller. Cleco notes that 70 Series tools require a 220/230 power supply to the controller.
• Q: Is this tool suitable for general repair or DIY use?
  A: This model is intended for high-torque industrial assembly and controlled fastening environments. For general vehicle repair or workshop use, a lower-torque impact wrench or smaller nutrunner is usually a better fit.
