The “original masonry” anchor that cuts its own threads into concrete, brick, or block. Maximum performance is achieved because the Tapcon anchor, the Condrive installation tool, and the carbide-tipped Tapcon drill bits are designed to work as a system. It is essential to use the Condrive tool and the correct drill bit to assure consistent anchor performance. Fast installation - drill a hole - drive an anchor. Packaged with one Tapcon “close tolerance” masonry drill bit per 100 anchors. Compatible for use in ACQ treated wood. Replaces small diameter expansion anchors, plugs and screws in light to medium duty applications. No need to pre-spot holes- and no inserts are required. Reversible and removable - can be installed close to an edge.
