The UltraCon+ Screw system is a complete family of screw anchors for light to medium duty applications in concrete, masonry block, brick, and wood base materials. The UltraCon+ is fast and easy to install and provides a neat, finished appearance. The UltraCon+ screw anchor is engineered with matched tolerance drill bits and installation tools designed to provide optimum performance. Concrete screws install quickly in a pre-drilled hole of the correct size and can be removed, re-used and reinstalled. The Blue Stalgard coating provides excellent exterior grade corrosion protection.
