Manufacturer's instructions specify correct torque settings for terminations especially in switchgear and consumer units. Under-torque screws result in a loose connection, possibly leading to arcing and hot spots; over tightened screws may damage the terminal. With the screws at the correct torque, you gain peace of mind in the knowledge of a job well done. Wiha carry out individual inspection, calibration and certification of every TorqueVario VDE tool. All the tools in the range adhere to the International Standards of accuracy BS EN 6789.
