Atlas Copco's unique Tensor motors give the Tensor range outstanding spindle speeds and, thus, help you achieve lower cycle times in your operation. Exceptional ergonomics in terms of balance, grip and low weight make the tools a favorite of the operators and increase individual productivity. All Tensor tools are equipped with LED’s that will indicate the tightening result, green light for tightening OK and red light for NOK. At Atlas Copco we believe that quality is the road to lowest cost of operation over time. A maintained Tensor tool produces the same performance year after year at minimum and predictable costs while ensuring highest possible uptime.

The second generation of Tensor tools, Tensor ST, also focusing on safety critical applications, was developed with low weight and productivity in mind
