“Hole” refers to a gap, an opening, an aperture, a port, a portal, a space or recess in a structure, a void in a structure, or the like. In certain embodiments, a hole can refer to a structure configured specifically for receiving something and/or for allowing access. In certain embodiments, a hole can pass through a structure. In other embodiments, an opening can exist within a structure but not pass through the structure. A hole can be two-dimensional or three-dimensional and can have a variety of geometric shapes and/or cross-sectional shapes, including, but not limited to a rectangle, a square, or other polygon, as well as a circle, an ellipse, an ovoid, or other circular or semi-circular shape. As used herein, the term “hole” can include one or more modifiers that define specific types of “holes” based on the purpose, function, operation, position, or location of the “hole.” As one example, a “fastener hole” refers to an “hole” adapted, configured, designed, or engineered to accept or accommodate a “fastener.” |
