A post anchor for anchoring a member to a post is disclosed. The post anchor comprises two segments: a drill end and a second end. The drill end is adapted to drill a hole in a post. A member is anchored to the post by attaching the member to the second end of the post anchor. The drill end is adapted to drill a hole in a post so that the post anchor is arranged in the hole without any axial play. An adhesive may be added to the hole to fill the spaces between the post and the drill end.
