A technique for securing a group of stator packs that are part of a stator core to construction bolts associated with a generator frame. The technique includes using a single wedge set to secure the group of stator packs to each construction bolt. Each wedge set includes a solid filler piece positioned within a groove on one side of a notch in the stator pack and a construction bolt filler piece having a convex shape portion configured to the shape of the construction bolt that accepts the construction bolt. A wedge member is forced between the filler pieces to secure the group of stator packs to the construction bolt.
