Cleco 50ESN85JD4 NeoTek Inline Corded Electric Nutrunner | 670 RPM | 12.5 - 61.9 (ft-lbs) Torque Range | 1/2" Square Drive

Built for controlled fastening in production assembly, the Cleco 50ESN85JD4 NeoTek inline corded electric nutrunner combines a 12.54–61.96 ft-lb torque range with 670 RPM free speed for medium-torque rundown work where repeatability matters more than raw breakaway power. It's a 1/2" square drive that accepts compatible industrial sockets, while the inline configuration helps operators keep the tool aligned with the fastener during vertical or fixture-assisted assembly. Transducer control measures applied torque electronically, supporting fastening processes where joint consistency, traceability, and controlled shutoff are required.

Part of Cleco’s NeoTek corded electric fastening platform, this 50 Series tool uses digital communication, configurable LED light rings, tactile and audible feedback, and onboard tool memory to support production-floor fastening control. The brushless motor helps reduce maintenance points compared with brushed motor designs, while internal temperature monitoring and preventive maintenance alerts help assembly teams manage tool condition before downtime interrupts the line.

• Repeatability and accuracy rated with 2.0 Cm/Cmk at +/- 7% for controlled assembly processes.
• 1 million cycles maintenance free rating helps support high-volume production environments.
• Configurable LED light rings give operators visual feedback for fastening status and process prompts.
• Tactile and audible operator feedback helps confirm tool response without relying only on screen-based indicators.
• Programmable multi-function buttons allow the tool to be configured for process-specific operator inputs.
• Onboard intelligent memory records tool setup values and cycle counts for maintenance scheduling.
• Modular assembly design supports serviceability when repair or maintenance is required.

Made in USA:

Applications:

• Automotive and vehicle assembly — controlled tightening of medium-torque bolted joints where repeatability and traceability are required.
• Heavy truck and trailer production — fastening brackets, frames, subassemblies, and drivetrain-related components within the tool’s torque range.
• Agriculture and lawn equipment manufacturing — running down fasteners on equipment assemblies where consistent torque output helps reduce rework.
• Large appliance and machinery assembly — production fastening on rigid joints using compatible 1/2" square drive sockets.
• Industrial assembly workstations — inline fastening in fixtures, vertical tool balancers, or operator-held processes that benefit from straight tool alignment.

FAQs:

• Q: What does transducer control mean on this Cleco nutrunner?
  A: Transducer control means the tool measures torque electronically during fastening. This helps support controlled shutoff and repeatable results in production assembly applications.
• Q: Is the 50ESN85JD4 a pneumatic tool?
  A: No. The 50ESN85JD4 is a corded electric NeoTek nutrunner, so it does not require shop air or an FRL. It should be matched with the correct Cleco controller and system components for the application.
• Q: What socket type fits this model?
  A: This tool uses a 1/2" square drive, so it accepts compatible 1/2" drive industrial sockets. Socket selection should match the fastener size, torque range, and production process requirements.
• Q: What is the torque range in Nm and ft-lbs?
  A: The manufacturer-listed torque range is 17.0–84.0 Nm, which corresponds to 12.54–61.96 ft-lbs. This places the tool in a medium-torque fastening range for controlled assembly rather than impact-style breakaway work.
• Q: Does this tool store production or maintenance information?
  A: Yes. The NeoTek platform includes onboard tool memory that records setup values and counts cycles, helping maintenance teams schedule service based on tool use.
