Energy Balance Of Screw Joints In Modern Component Systems

Energy Efficiency today is important for engineering design of new technical component systems; almost any design engineer knows about this. But in many cases the (design) engineers do not think about the significant contribution of optimized fastening systems. This paper shows the fundamental influences and gives examples with numeric values. Conclusions with respect to all main steps in life time are drawn which should be considered for future developments of fastening systems in energy efficient products.
