STR Series

The Atlas Copco Tensor STR series represents the latest evolution of the Tensor ST family, offering improved ergonomics and smart tightening features. These nutrunners include innovations such as TrueAngle (for angle compensation) and TurboTight (to minimize torque reaction), which help operators work faster and more safely. The STR tools connect directly to the Power Focus 6000 controller, allowing full integration of their capabilities like multi-step tightening and real-time data feedback. With options like two-trigger safety designs and a refined balance, the Tensor STR series elevates productivity and comfort while maintaining the high precision required for critical bolting applications.
