Claim:
A method of introducing a post anchor into a post, the method comprising: providing a post and a post anchor, wherein the post comprises an elongated block defined by a top surface, a bottom surface, at least one side surface between the top surface and the bottom surface, and a longitudinal axis extending between the top surface and the bottom surface, wherein the post anchor comprises a first section which includes a self-drilling drill bit section adapted to form a drill hole, the self-drilling drill bit section having an outer surface and defining at least one helical groove, the helical groove extending into the drill bit section and configured to aid in removal from the drill hole of chips or material cut during the drilling process, the drill hole having a surface and a second section for fastening to an element, wherein the diameter of the drill bit section is substantially the same as the diameter of the surface of the drill hole, wherein the post anchor is flangeless, and wherein the drill bit section is arranged within the post, the second section extending over the top surface of and away from the post; forming a drillhole in the post with the drill bit section, wherein the drillhole extends from and through the top surface and along the longitudinal axis, and wherein the outer surface of the drill bit section is substantially in contact with the surface of the drillhole; and introducing adhesive into the drillhole with the drill bit section inserted so as to take up, by filling, any remaining radial play and axial play of the drill bit section in the drillhole, and wherein the helical groove is at least partially filled with an adhesive after the drill hole is formed.
