The fact that more and more fastening points have to be tightened with a prescribed force (Nm, also called "torque") is due to the legislator, which imposes increasingly higher safety requirements and due to the changed use of material, smaller and in particular lighter. See especially the increase in use of aluminum and carbon fiber, which require a completely different approach in processing than the more common materials. It is therefore important that you work with calibrated torque wrenches with an official inspection report. WERA meets this requirement.
