Atlas Copco ETV ST81-150-13 Angle Electronic Nutrunner

Atlas Copco's ETV ST81-150-13 is a high‑torque, angle‑head electronic nutrunner designed for precise torque control in tight spaces. Powered by a 1500 W AC motor at 200 V (3‑phase), it delivers a torque range of 30–160 Nm (22–117 ft‑lb) at speeds up to 380 rpm, with a 1/2" output and a square, male drive. The transducer‑based shut‑off system provides repeatable torque termination for consistent assemblies, and the tool belongs to the Tensor ST family, model type Angle, featuring an angle head and ST‑series mechanics. Its bare tool length is 555 mm, height 65 mm, and a center‑to‑spindle distance of 26 mm, weighing about 7 lb (3.18 kg). Manufactured in Sweden, the ETV ST81-150-13 is suited for assembly tasks requiring controlled torque in restricted spaces and supports both automated and manual bolting applications across industrial settings.
