A method of mounting a base plate to a biologic material comprising inserting and retaining a threaded nut within a first through hole of a base plate, wherein the first hole is at least partially defined by an interior circumferential wall and the threaded nut comprises a cylindrical inner wall at least partially defining a second through hole inserting a screw through the first and second through holes so that at least a portion of a threaded shaft extends beyond the interior circumferential wall of the base plate rotating the screw with respect to the base plate and the threaded nut to operatively engage a head of the screw with the threaded nut inserting the screw into a biologic substrate and locking an angular orientation of the screw with respect to the base plate.
