A system and method are provided for coupling a hub to a main shaft of a wind turbine. Accordingly, a plurality of fasteners are arranged within corresponding through holes of the hub of a wind turbine. At least one circumferential ridge segment is arranged radially adjacent to the head sections of the plurality of fasteners so as to resist a torque applied to each of the plurality of fasteners. A connection mechanism is utilized to secure the plurality of fasteners within the plurality of through holes so as to limit an axial translation of the plurality of fasteners prior to the coupling of the hub to the main shaft.
