Summary:A bone plate includes at least one hole extending through the bone plate from an upper plate surface to a lower plate surface along a central hole axis that is oriented along an axial direction. The at least one hole defined by an interior surface of the bone plate. The interior surface further defining a plurality of columns sequentially located about a circumference of the interior surface and a plurality of recesses located circumferentially between the columns. Each of the columns defines a plurality of thread segments each defining a root, a first thread surface extending from the root to a first crest, and a second thread surface extending from the root to a second crest. At least a portion of the first and second thread surfaces are offset from one another at a thread angle. The thread angle of at least one of the thread segments is in a range of about 5 degrees to about 59 degrees.
