The Hillman Group Power Pro Blue Flat Head Concrete Screw (MPN 376526) is a self-tapping fastener designed for light to medium-duty anchoring in concrete, brick, and block. Constructed from heat-treated carbon steel, it features a blue epoxy coating, often referred to as Climacoat, for superior corrosion resistance and durability, making it suitable for outdoor applications and use with ACQ treated lumber. The screw has a flat head with under-head micro-nibs to facilitate clean countersinking and a star drive recess to minimize stripping during installation. Its wide, serrated hi-low threads are designed to cut cleanly and quickly into masonry, providing high pullout and shear strength. This Power Pro concrete screw is ICC-ES Code Compliant and approved by various building codes, including those in California and Florida. Installation typically requires a pre-drilled hole, such as a 5/32-inch diameter pilot hole for this 3/16-inch diameter screw.
