Hex Washer Head / Slotted Concrete Screws
Concrete screws are designed for use in concrete, brick or block. A masonry bit and preferably a hammer drill is used to drill a hole slightly smaller than the screw size. The concrete screw should be screwed slowly into the pre-drilled hole after the hole is blown clear of particles and debris. The blue coating helps to resist rust and corrosion. Other popular screws include: license plate screws, torx screws and sheet metal screws.
