Steel Flat Head Tapping Screws for Concrete, Block, and Brick
These blue and silver ultra-corrosion-resistant coated steel screws stand up to wet environments. These screws are beveled under the head for a flush finish in countersunk holes. Drive into a hole with a hammer drill or socket wrench, or use a specialized tool set (sold separately). Pull-out strength and shear strength values are 25% of the ultimate values.
Blue acrylic coated anchors are also known as Tapcons.
