Concrete screws For quick and easy fastening of fixtures to concrete, brick and blockwork. The screw is hardened and is tightened directly into a pre-drilled hole. It is fully threaded with a “hi-low” thread that makes installation easier. Increased anchor depth generally results in increased loading capacity. A hammer screwdriver or impact wrench are recommended for installation. For installation in a material other than concrete, a tensile test should be performed to obtain a suitable practical loading capa- city. Pan head with Torx head or hexagon head with flange.
