Cleco 70ESN850SD8 NeoTek Corded Electric Nutrunner | 128 RPM | 157.1 - 626.9 (ft-lbs) Torque Range | 1" Square Drive

When large fasteners require controlled torque instead of impact-style tightening, the Cleco 70ESN850SD8 NeoTek 70 Series inline corded electric nutrunner delivers a 213 - 850 Nm / 157.1 - 626.9 ft-lbs torque range for high-torque assembly work. It's a 1" square drive accepts compatible industrial sockets, while the inline body keeps the tool aligned with the fastener for straight-on rundown in fixture, reaction-arm, or suspended tool setups.

The NeoTek fastening system is built for smart assembly environments where repeatability, tool feedback, and production data matter. This 70 Series inline corded nutrunner provides 125 r/min speed for controlled tightening on large joints, with digital communication, configurable LED light rings, data logging through on-board tool memory, and preventive maintenance alerts to help production and maintenance teams manage uptime.

• Digital communication supports reliable performance within Cleco controller-based assembly systems.
• Internal temperature monitoring helps protect the tool during repeated high-torque fastening cycles.
• Configurable LED light rings provide visual tool status feedback for operators and line supervisors.
• Data logging with on-board tool memory supports production traceability and maintenance review.
• Preventive maintenance alerts help teams schedule service before tool issues interrupt production.
• Fully programmable features, including high-output LED light rings, audible alerts, and handle vibration, provide operator feedback during assembly work.
• Inline configuration supports straight-on fastening where the tool is used with fixturing, balancers, reaction devices, or production tooling.
• 70 Series tools require a 220/230 power supply to the controller.

Made in USA:

Applications:

• Heavy machinery assembly: Controlled tightening of large bolts where 157.1 - 626.9 ft-lbs of torque capacity is required.
• Automotive and off-highway production: Fastening structural, axle, drivetrain, and frame-related joints in controlled assembly environments.
• Heavy truck and trailer manufacturing: Straight-on tightening of large fasteners where torque repeatability and production feedback are required.
• Rail and transportation equipment: Assembly of bolted components that require documented torque output and consistent rundown behavior.
• Industrial tooling and MRO departments: Replacement or standardization within existing Cleco NeoTek 70 Series corded electric fastening systems.

FAQs:

• Q: Is the Cleco 70ESN850SD8 an inline or angle nutrunner?
  A: This model is listed as an inline corded nutrunner. Inline tools are commonly used where the operator or fixture can approach the fastener straight on.
• Q: What does the 157.1 - 626.9 ft-lbs torque range mean?
  A: It is the tool’s specified fastening torque range in foot-pounds. The same range is listed in metric as 213 - 850 Nm.
• Q: Is this a pneumatic tool?
  A: No. The 70ESN850SD8 is a corded electric NeoTek nutrunner used with a compatible controller, not a compressed-air nutrunner.
• Q: What power supply is required?
  A: Cleco notes that 70 Series tools require a 220/230 power supply to the controller. Confirm controller model, regional voltage, and plant electrical requirements before installation.
• Q: What sockets should be used with this nutrunner?
  A: The tool has a 1" square drive, so it should be paired with compatible 1" drive impact-rated sockets and any required reaction tooling for the joint.
