Abstract: In bolted joints having a plurality of bolts, the receiving bores for the bolts in the parts to be joined are usually made by joint boring of the bolt eyes of these parts. In cases in which this approach is not possible, an offset of the bolt bores arises. The proposed solution is intended to compensate for this offset during the assembly of the parts.
