Abstract: A wind turbine blade portion connector is configured to attach a first blade portion to a second blade portion of a wind turbine blade. The connector comprises a double-ended threaded stud bolt and a spring. The bolt has two threaded portions with opposing threads configured to be threadedly engaged with respective threaded holes of the first blade portion and the second blade portion. The bolt also has a tool engagement feature fixed in rotation with and disposed between the two threaded portions for rotating the bolt, and a bearing surface disposed between the two threaded portions. The spring is configured to bear against the bearing surface and exert a tensile force on the first and/or second threaded portions of the stud bolt, in a direction parallel or co-axial to a longitudinal direction of the stud bolt when disposed between the bearing surface and the first or second blade portion.
