Caliburn concrete screws are professionally engineered fasteners with a patented thread design for ease of driving the screw in concrete and similar applications. Available in three different head styles for multiple applications. Caliburn, Caliburn PH and Caliburn XL are Climatek coated for high corrosion resistance. Caliburn's uncompromised draw and pull-out strength make it possible to be used in jobs which previously required an anchor. The screws aggressive thread design afford it the ability to be removed and reinserted into the same pilot hole numerous times without the concern of the fastener breaking or the threads wearing.
