Tapper Concrete Screw Anchors are manufactured for top performance in masonry-based applications. These fasteners are engineered for multi-material use, securely anchoring into concrete, brick, and block, with a Perma-Seal coating that provides long-lasting corrosion protection. The unique thread design ensures a steady drive and reduces torque during installation, making them ideal for window installations, rails, door frames, and more, with a tapper bit included in each package to simplify the process.
