Clean out any debris from the hole, then insert the anchor bolt, ensuring it is positioned correctly. If using expansion anchors, tighten the bolt to expand the anchor into the concrete. For adhesive anchors, inject the adhesive into the hole before inserting the bolt and allow it to cure as per the manufacturer's instructions.
