Abstract
A structure is provided for retaining one or more fasteners in a corresponding one or more apertures of a first fan element so that, as the first fan element is attached to a second fan element by engaging the fasteners with the second fan element, the fasteners cannot inadvertently fall out of the apertures. The first fan element can thus be attached to the second fan element without the installer having to insert fasteners through apertures in the first fan element while maintaining registration between the first fan element and the second fan element. According to one aspect, the first fan element is a fan blade arm and the second fan element is a fan center hub. According to another aspect, one or more of the fasteners are machine screws.
