Built for precision assembly stations that need fast rundown with verified torque control, the Cleco 50ESN28FD3 NeoTek Inline Corded Electric Nutrunner combines a 4.1 - 20.6 ft-lbs torque range with 2,125 RPM speed and a 3/8" square drive. The inline body supports straight-line fastening where the tool must stay aligned with the joint, while transducer control measures torque directly for repeatable tightening in production environments.
Part of the NeoTek 50 Series, this corded electric nutrunner is suited to assembly work where torque accuracy, traceability, and operator feedback matter more than breakaway power. Features such as configurable LED light rings, audible alerts, handle vibration, on-board data logging, and preventive maintenance alerts help operators confirm fastening status and help supervisors manage tool performance on the line.

Applications:
- Automotive assembly stations fastening medium-range bolted joints where speed and torque verification are required.
- Aerospace and transportation manufacturing cells using inline tools for straight-access fastening operations.
- Appliance and equipment assembly lines where repeatable rundown and traceable tightening data support quality control.
- Industrial production environments using corded electric nutrunners with controllers for batch fastening, error proofing, and process monitoring.
- Fixture-based or bench assembly work where the 3/8" square drive and 0.64" side-to-center dimension support compact joint access.
FAQs:
- Q: What does transducer control mean on this Cleco nutrunner?
A: Transducer control means the tool measures torque directly during fastening. This helps improve repeatability and supports production environments where each joint must meet a controlled torque target. - Q: Is the 50ESN28FD3 better for tightening or loosening fasteners?
A: This tool is primarily for controlled tightening in assembly applications. It is not intended to replace an impact wrench for removing seized or high-breakaway fasteners. - Q: What applications fit the 4.1 - 20.6 ft-lbs torque range?
A: This range fits medium-light production fastening tasks where consistent torque is more important than maximum power. Typical examples include automotive components, appliance assemblies, equipment panels, and other controlled bolted joints within the specified range. - Q: Does the inline configuration matter?
A: Yes. An inline nutrunner keeps the tool body aligned with the fastener, which helps in straight-access applications, bench assembly, and fixtured stations where a pistol or right-angle tool may not be the best fit. - Q: Does this tool require a controller?
A: NeoTek corded electric assembly tools are part of a controlled fastening system and are typically used with a compatible Cleco controller. Please verify controller compatibility before ordering.
