Conquest large diameter concrete screws are high strength removable concrete anchors made from hardened steel. Installation is much quicker than a traditional wedge anchor due to the fact you can install these screw anchors with an impact wrench instead of requiring a torque wrench. Conquest large concrete screws are easily removable, making them exceptionally great for installing temporary fixtures, machinery, pallet racking, shelving and more. Serrated edges on the leading threads of the anchor cut into the concrete, requiring less torque for installation. This zinc coating is designed for installation in dry interior environments only.
