1. A bone plate, comprising:
a plate body that defines a combination hole comprising a locking hole and a compression hole that intersect one another and each extends from an outer surface of the plate body to a bone-facing surface of the plate body, wherein the locking hole and the compression hole extend away from each other along a longitudinal axis,
the plate body further defining 1) a locking surface that defines the locking hole, 2) a second surface that defines the compression hole, and 3) an intersection boundary between the locking surface and the second surface;
wherein the locking surface further defines:
first, second, and third columns sequentially located about a central axis of the locking hole, each column having a first side, a second side opposite the first side, and a column length measured from the first side to the second side;
a first recess extending from the second side of the first column to the first side of the second column;
an additional recess extending from the second side of the third column to the first side of the first column;
plate threads that traverse each of the columns and at least portions of the first recess and the additional recess; and
a transition zone that is spaced from the first column along a longitudinal direction oriented along the longitudinal axis and extends to the intersection boundary, wherein the plate threads traverse the locking surface in the transition zone, and the locking surface in the transition zone is elongated such that the column lengths of the second and third columns is greater than the column length of the first column.
