Bolted connection for connecting two wind turbine components by bolts

A wind turbine, comprising:

• a wind turbine generator;
• a rotatable hub connected to the wind turbine generator, the rotatable hub comprising a blade bearing;
• a rotor blade supported by the blade bearing;
• and
• at least one bolted connection arranged to connect the rotor blade to the blade bearing, said at least one bolted connection comprising a plurality of bolts arranged in a circumferential direction, each bolt comprising a bolt shaft and a plurality of bolt threads, each bolt thread arranged to carry a load to connect the rotor blade to the blade bearing,
• wherein the bolt threads comprise a transition region between the bolt shaft and the bolt threads, wherein the transition region is tapered in a direction divergent from the bolt shaft as one travels along the bolt shaft in a direction from a head of the bolt towards an end of the bolt opposite the head of the bolt,
• wherein the length of the tapered transition region starts from the first one of the threads closest to the head of the bolt up to the fourth one of the threads, wherein each bolt thread from the first one of the threads to the fourth one of the threads is arranged to carry a load to connect the rotor blade to the blade bearing, wherein the first one of the threads comprises a smaller diameter relative to the fourth one of the threads, wherein a remaining threaded region extending beyond the tapered transition region has a constant diameter.
