Product Overview
The Hillman Fasteners Power Pro Flat Head Concrete Screw, MPN 376540, is engineered for secure fastening into concrete, block, and brick. Constructed from heat-treated carbon steel, this 5/16" diameter, 2-3/4" long screw features a flat head with under-head micro-nibs for flush, debris-free countersinking. Its star drive design provides six contact points to minimize cam-out during installation. A blue epoxy coating offers superior corrosion resistance, making it suitable for both interior and exterior applications, including those involving treated lumber. Wide, serrated threads cut efficiently into masonry, while threading to the tip ensures quick penetration and strong holding power. This screw is ICC-ES Code Compliant and approved for use with AC257 treated lumber.
