hen tensioning a bolt to a specific torque, it is important to be aware of the factors that must be in place to avoid under tightening or overtightening the bolt. A bolt that is not correctly tensioned to a torque can have major consequences. Hydraulic torque tensioning of bolts is still the method that is used in the vast majority of places when we talk about torque tensioning over XXX Nm. Torque tensioning is the same, regardless of whether it is hydraulic tensioning or using electric/battery powered nut runners. However, some precautions and principles that must be observed. We train customers and partners about correct torque tensioning, because we know what the consequences would be if a bolt is either under tightened or overtightened.
