Abstract
A wind turbine includes a plurality of turbine blades, with each of the blades having a root flange that attaches to a flange of a rotor hub by a plurality of circumferentially spaced blade bolts. The blade bolts have opposite cylindrical end sections engaged within the rotor hub flange and blade root flange, respectively, and a non-cylindrical shank extending between the cylindrical end sections. At least one flattened side is defined in the shank along a longitudinal axis of the bolt.
