When a production cell needs controlled tightening in the low-to-mid torque range, the Cleco 50ESN43GD3 NeoTek Inline Corded Electric Nutrunner delivers 6.6 - 31.7 ft-lbs of fastening torque with a 1,375 RPM free speed for efficient rundown before final torque control. Its 3/8" square drive accepts compatible square-drive sockets, while the inline configuration keeps the tool aligned with the fastener for straight-access assembly work, bench stations, and fixtured production operations.
As a 50 Series NeoTek transducer-controlled tool, the 50ESN43GD3 is built for assembly environments where accuracy, operator feedback, and fastening data matter. Transducer control measures torque directly during the fastening cycle, helping support repeatable tightening and process validation. Configurable LED light rings, tactile feedback, audible alerts, programmable buttons, and onboard memory give operators a clear fastening status while helping production teams manage quality requirements across repeated cycles.

Applications:
- Automotive component assembly where repeatable tightening and fastening feedback are required on medium-range joints.
- Appliance and equipment manufacturing for controlled fastening of housings, brackets, frames, and subassemblies.
- Aerospace and transportation production cells using inline tools for straight-access bolting operations.
- Industrial assembly benches where a 3/8" square drive nutrunner is preferred for socket-based fastening.
- Quality-controlled manufacturing lines that require torque traceability, operator prompts, and controller-based fastening strategies.
FAQs:
- Q: What type of fastening work is the Cleco 50ESN43GD3 used for?
A: This tool is used for controlled tightening in production assembly. Its 6.6 - 31.7 ft-lbs torque range fits applications that need more torque than small electronic assembly tools but less power than large structural bolting tools. - Q: What does the 3/8" square drive mean?
A: The output drive is the part of the tool that accepts sockets. A 3/8" square drive works with compatible 3/8" drive sockets used for nut and bolt fastening within the tool’s torque range. - Q: How does this model differ from the 50ESN28FD3?
A: The 50ESN43GD3 has a higher torque range of 6.6 - 31.7 ft-lbs and runs at 1,375 RPM. The 50ESN28FD3 is faster at 2,125 RPM but covers a lower 4.1 - 20.6 ft-lbs torque range, so model selection depends on the torque requirement of the joint. - Q: Is this nutrunner intended for removing stuck fasteners?
A: No. This is a precision assembly nutrunner for controlled tightening, not an impact wrench for breakaway work. Use it for joints that fall within the specified torque range and require controlled rundown and final torque. - Q: Does this tool need a compatible controller?
A: Yes. NeoTek corded electric nutrunners are part of a controlled fastening system and are typically paired with a compatible Cleco controller. Confirm controller, cable, and system compatibility before ordering.
