SR Series

The Atlas Copco Tensor SR Series comprises small, high-speed electric nutrunners equipped with transducers for precise torque and angle measurement. These tools are specifically designed to deliver top-tier performance (accuracy and repeatability) in tight or confined areas where larger tools can't fit. Despite their compact size, Tensor SR nutrunners provide impressive power-to-weight ratios, enabling them to fasten bolts quickly while maintaining an industry-leading accuracy. They come in straight and angle configurations with slim profiles, making them ideal for applications like engine assembly or electronics manufacturing, where many fasteners are tucked into recesses or closely spaced. When connected to an Atlas Copco controller, they offer advanced tightening strategies and immediate feedback on each fastening, allowing manufacturers to meet strict quality requirements even in the most space-constrained operations.
