The standard gives the design engineer help in the identification and separation of the most loaded one-screw bolt connection within a field (multi-bolt connection). This is done by the description of different calculation methods and their systematic presentation regarding the method and the possibilities and limitations. With these calculated stress and calculatory values, the quality of the subsequent functional and reliable design in accordance with VDI 2230 Part 1 is improved significantly. The standard applies to high-strength bolted joints made of steel with screw thread, i.e. for property classes 8.8 to 12.9 or 70 and 80 and a frictional transmission of the working load which basically acts on the clamped components or on the structure. As regards bolts made of other materials, or with lower strength grades or with strengths which deviate from DIN ISO 898-1, the standard can be applied analogously.
