The Atlas Copco STwrench is much more than a standard transducerized hand-held nutrunner. Providing a whole new approach to manual assembly applications. Due to its modular design, you can build the STwrench to meet your exact requirements and create a tool that perfectly matches your applications. Use the STwrench for production to get full traceability of the entire tightening operation, including torque control, angle control and yield control. Or build your wrench to just tighten your joint with high torque accuracy. Or use it for quality control to check residual torque, to perform joint analysis, including joint behaviour and stiffness, to set the correct tightening parameters for production and to test the reproducibility of joint stiffness on the benches.
