Vdi 2230 Part 1 Pdf

The selection of the tightening method (e.g., torque wrench, angle-controlled tightening, or impact wrench) is critical, as it determines the scatter of the preload force. This scatter is described by the tightening factor αA. For example, a simple impact wrench can cause a scatter of over 60%, while a precise torque wrench is much more accurate.
