Industrial ST61-28-10 Right Angle Electric Nutrunner

Industrial ST61-28-10 Right Angle Electric Nutrunner (ETV ST61-28-10) is Atlas Copco’s electric angle nutrunner designed for high-precision tightening in constrained spaces. It uses a 3/8 in square drive and delivers a torque range of 6–29 Nm (4–21 ft-lb) with a no-load speed of 1450 rpm, enabling fast yet controlled tightening on fasteners from small to medium sizes. Weighing about 1.3 kg (2.9 lb) and measuring roughly 440 mm in length with a 42 mm profile, the tool balances compact reach with stability for operator comfort in hand-held or fixtured setups. The right-angle configuration directs torque through a compact head to reach fasteners situated in crowded assemblies, making it suitable for automotive subassemblies, electronics enclosures, and other manufacturing tasks where space is tight. As part of the Tensor ST line, it is designed to integrate with Atlas Copco’s control ecosystems and accessories, and is fully compatible with the Power Focus 6000 controller for tightened process control and data traceability. Accessories such as sockets, bit holders, and collets designed for 3/8 in drive are compatible, enabling a wide range of fastening tasks on common 6–29 Nm ranges.
