When tightening bolted connections, it is all about the right conversion from torsion to bolt load. Our tools always deliver the desired amount of torque, but a lot of the energy is wasted due to friction. In “standard” situations, without using the right lubricaion, only 10% of torsion is turned into clamping force! Needless to say that this a far from economical. With use of the right lubrication, efficiency can be increased drastically.
