A bone plate, comprising: an outer surface and a bone-facing surface opposite the outer surface; and an interior surface that defines a hole that extends from the outer surface to the bone-facing surface along a central hole axis, wherein the interior surface further defines: a ramp extending from the outer surface toward the bone-facing surface; plate threads extending from the ramp toward the bone-facing surface, wherein the plate threads are configured for optional locking engagement with external threads on a first head of a locking bone fixation member, a contact profile defined at least by the ramp in a reference plane that extends along the central hole axis, wherein the contact profile is spaced from the central hole axis in an offset direction perpendicular to the central hole axis, and the contact profile is configured to translate the bone plate in the offset direction responsive to contact with an exterior surface of a second head of a compression bone fixation member as the second head advances within the hole along an insertion axis that is offset from the central hole axis in the offset direction, wherein the hole has a polygonal hole profile in a second reference plane that is orthogonal to the central hole axis characterized in that the polygonal hole profile is a trigonal hole profile. an outer surface and a bone-facing surface opposite the outer surface; and an interior surface that defines a hole that extends from the outer surface to the bone-facing surface along a central hole axis, wherein the interior surface further defines: a ramp extending from the outer surface toward the bone-facing surface; plate threads extending from the ramp toward the bone-facing surface, wherein the plate threads are configured for optional locking engagement with external threads on a first head of a locking bone fixation member, a contact profile defined at least by the ramp in a reference plane that extends along the central hole axis, wherein the contact profile is spaced from the central hole axis in an offset direction perpendicular to the central hole axis, and the contact profile is configured to translate the bone plate in the offset direction responsive to contact with an exterior surface of a second head of a compression bone fixation member as the second head advances within the hole along an insertion axis that is offset from the central hole axis in the offset a ramp extending from the outer surface toward the bone-facing surface; plate threads extending from the ramp toward the bone-facing surface, wherein the plate threads are configured for optional locking engagement with external threads on a first head of a locking bone fixation member, a contact profile defined at least by the ramp in a reference plane that extends along the central hole axis, wherein the contact profile is spaced from the central hole axis in an offset direction perpendicular to the central hole axis, and the contact profile is configured to translate the bone plate in the offset direction responsive to contact with an exterior surface of a second head of a compression bone fixation member as the second head advances within the hole along an insertion axis that is offset from the central hole axis in the offset direction, wherein the hole has a polygonal hole profile in a second reference plane that is orthogonal to the central hole axis characterized in that the polygonal hole profile is a trigonal hole profile.
