1. A bone plate, comprising:
an outer surface and a bone-facing surface opposite the outer surface; and
an interior surface that defines at least one hole that extends from the outer surface to the bone-facing surface along a central hole axis, wherein the interior surface further defines:
plate threads extending between the outer surface and the bone-facing surface, wherein the plate threads are configured for locking engagement with external threads on a head of a locking bone screw;
first, second, and third columns sequentially located about the central hole axis;
a first corner extending tangentially from a first side of the second column to a second side of the first column;
a second corner extending tangentially from a second side of the third column to a first side of the first column, wherein the first corner and the second corner are substantially equidistantly spaced from the central hole axis at a first distance measured along a radial direction perpendicular to the central hole axis, and the plate threads extend across the first, second, and third columns and across the first corner and the second corner; and
a recess located between the second and third columns and facing the first column, wherein an apex of the recess is spaced from the central hole axis at a second distance that is greater than the first distance, such that the recess circumferentially interrupts at least a portion of a thread-form of at least one of the plate threads.
