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.
Type: Inline Corded Electric Nutrunner | Series: NeoTek 70 Series | Model: 70ESN850SD8 | Torque Range: 213 - 850 Nm / 157.1 - 626.9 ft-lbs | Speed: 125 r/min | Output Drive: 1" Sq. Drive | Weight: 7.60 kg / 16.76 lb | Length: 610 mm / 24.01 in | Side to Center: 38.0 mm / 1.49 in
Features:

- 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.
