There are hardly any appliances, whose manufacturing process does not include the assembly of some parts, units using bolts. The quality of bolt connections has a great impact on the overall usability, lifetime and reliability of the final product. It is not unusual that a worker drives hundreds of screws a day. In such a workstation it is inevitable that some bolts are left out or not properly pre-stressed.The aim of this appliance is to prevent the application of wrong torque. The torque wrench controller is adjusted to the workstations and their work phases. At the workstation the torque wrench must be applied at the number sent by the server and specified for the given part/unit.
