Product Overview
The Hillman Power Pro Blue Flat Head Concrete Screw, model 376531, is designed for direct fastening into concrete, block, brick, and masonry materials. Constructed from heat-treated carbon steel, this 1/4 inch diameter by 1-3/4 inch length fastener features a flat head with underhead micro-nibs to facilitate clean countersinking. The screw is finished with a blue epoxy coating, providing superior corrosion resistance that surpasses 1500 hours of salt spray testing and makes it suitable for use with AC257 treated lumber and outdoor applications. It utilizes a star drive for secure, high-torque installation. Its wide, serrated threads and mid-crossband threads ensure fast, stable, and clean engagement. This concrete screw is ICC-ES Code Compliant (ESR-4340 for concrete, ESR-4339 for masonry, ESR-4357 for chemically treated wood), and is approved by California and Florida Building Codes.
