1. A bone plate comprising:
a bone-contacting surface;
an upper surface opposite the bone-contacting surface; and
a hole extending from the upper surface to the bone-contacting surface, the hole having a plurality of scalloped regions spaced around a circumference of the hole being separated by a respective screw-engaging member that is plastically deformable to form an interference connection with a screw head, the screw-engaging member having a converging-diverging profile that extends along a central axis of the hole, the hole further defining a countersink that extends from the upper surface to an intermediate surface, wherein the intermediate surface extends into the hole along a plane that is perpendicular to the central axis, and the screw-engaging member extends between the intermediate surface and the bone-contacting surface.
