When high-torque assembly needs traceable fastening instead of impact-style tightening, the Cleco 70ESN355SD8 NeoTek Inline Corded Electric Nutrunner delivers controlled output for production bolting, heavy machinery assembly, and precision fastening stations. This 70 Series inline tool provides a 65.6 – 261.0 ft-lbs torque range, giving technicians the capacity to tighten large fasteners while staying within a programmable fastening window. Its 335 RPM speed supports controlled run-down before final torque, while the 1″ square drive accepts compatible industrial sockets for high-torque assembly work.The NeoTek fastening system combines corded electric power with transducer control, which uses internal torque sensing to help verify fastening performance during assembly. Configurable LED light rings, audible alerts, handle vibration, on-board tool memory, and preventive maintenance alerts help operators and production teams track fastening status, tool condition, and process feedback without relying on guesswork.Type: Inline Corded Electric Nutrunner | Brand: Cleco | Series: NeoTek 70 Series | SKU: 70ESN355SD8 | Torque Range: 89 – 354 Nm / 65.6 – 261.0 ft-lbs | Speed: 335 RPM | Output Drive: 1″ Square Drive | Weight: 7.60 kg / 16.76 lb | Length: 610 mm / 24.01 in | Side to Center: 38.0 mm / 1.49 inFeatures:Repeatability and accuracy with 2.0 Cm/Cmk at +/- 7% for controlled fastening processes where torque consistency matters.21% lighter tool and cable system than the existing tool family, helping reduce handling strain during repeated assembly cycles.Digital communication supports reliable performance feedback between the tool and compatible fastening system components.Internal temperature monitoring helps protect the tool during production use by tracking heat buildup inside the assembly system.Configurable LED light rings provide visual status feedback so operators can quickly identify fastening results or process prompts.Data logging with on-board tool memory supports traceability for quality teams managing assembly records and fastening history.Preventive maintenance alerts help maintenance teams plan service before tool condition affects line productivity.Made in USA: Applications:Heavy machinery assembly tightening large structural and mechanical fasteners where controlled torque is required.Automotive and transportation production fastening high-load joints on frames, driveline components, and subassemblies.Rail and off-highway equipment manufacturing controlled bolt-up work on equipment where torque traceability supports quality documentation.Industrial assembly lines repeat fastening operations that benefit from LED feedback, data logging, and preventive maintenance alerts.Tool cribs and production maintenance replacing older high-torque corded tools with a lighter NeoTek tool and cable system.FAQs:Q: What type of fastening work is the 70ESN355SD8 used for?A: This tool is used for controlled high-torque assembly, not impact loosening. It is suited to production bolting where torque range, repeatability, and fastening feedback are more important than breakaway force.Q: What does transducer control mean on a Cleco NeoTek nutrunner?A: Transducer control means the tool uses internal torque sensing to support controlled fastening and process verification. This helps assembly teams monitor torque results instead of relying only on time, speed, or operator feel.Q: Does the 1″ square drive fit standard sockets?A: The tool uses a 1″ square drive, so it requires compatible 1″ drive industrial sockets rated for the torque and application. Always match the socket, fastener, and reaction setup to the torque range being used.Q: Is this a pneumatic nutrunner?A: No. The 70ESN355SD8 is a corded electric inline nutrunner, so it does not require compressed air or an FRL. It is part of Clecos NeoTek corded electric fastening platform.Q: Are controller, cable, sockets, or reaction accessories included?A: The provided product data identifies the nutrunner and its specifications, but does not confirm included accessories. Confirm controller, cable, socket, and reaction accessory requirements before publishing or ordering. .spec-accordion{width:100%;max-width:1200px;margin:1em
