Atlas Copco ETD S9-4000-38CTADS Electric Nutrunner

Atlas Copco ETD S9-4000-38CTADS Electric Nutrunner is a straight inline electric tightening tool with a 1-1/2 in square drive, engineered for high-torque fastening in automated assembly. It provides a torque range from 730 ft-lb up to 2,950 ft-lb (approximately 990–4,000 Nm) at a fixed speed of 18 rpm, enabling precise, repeatable joints. The tool's compact footprint — 654 mm in length with a 68 mm center-to-center distance — and its inline form factor support tightening in tight workspaces, while its pistol-type design ensures a stable grip and comfortable operation with an 8/12 spline mounting option. Weight is 47.8 lb (about 21.7 kg), and it originates from Sweden. For transport and storage, the packaged dimensions are around 103 cm × 19 cm × 23 cm with a total package weight of 27 kg. Acoustic and ergonomic performance are notable, with sound pressure under 70 dB(A) and vibration under 2.5 m/s² during operation, contributing to comfortable long-run use on busy lines.
