Atlas Copco ETV SL21-20-10 D67 Tensor Nutrunner

The Atlas Copco ETV SL21-20-10 Tensor Nutrunner is a compact, angle-head tightening tool engineered for precise, torque‑controlled assembly in restricted spaces. It delivers a torque range from 4 to 20 Nm with a torque scatter of ≤5% over a 3‑second window, and uses a 3/8" square drive with a 14 mm center distance (CS) and an overall length of 285 mm. Weighing about 0.95 kg, it runs on a 140 W, 35 V AC motor (three‑phase) and includes a transducer-based shut‑off system to terminate tightening at the preset torque. As part of Atlas Copco’s Tensor SL family, the SL21-20-10 features an angle output and male square drive for versatile fixture integration, balancing light weight with robust performance for repetitive fastening tasks. Acoustic and vibration performance meet industry standards, with a sound pressure under 70 dB(A) (ISO15744) and vibrations under 2.5 m/s² (ISO28927-2). This model is well suited to small‑ to mid‑sized fasteners in automotive, electronics, and general manufacturing environments where consistent torque delivery and operator comfort are critical.
