Perma-grip® is the largest selling medium duty concrete anchor in some parts of the United States. Most of the sales have been to STAFDA distributors and lumber yards. Any distributor that sells Tapcon® can sell Parma-grip® alongside it because most screw anchors are never removed. The installer of these anchors will prefer Perma-grip® instead of concrete screws because of the “setting” sensation with the hammer.
