Built for strength, speed, and superior corrosion resistance, the Power Pro 376543 Concrete Screw Anchors are the go-to solution for fastening into concrete, masonry, and treated lumber. With a flat head design for flush finishes and a blue epoxy coating for long-lasting durability, these anchors are ideal for both residential and commercial construction projects.

Engineered for Maximum Performance

• Heat-treated carbon steel construction delivers exceptional tensile strength and load-bearing capacity.
• Blue epoxy coating offers 50% greater corrosion resistance than standard zinc-plated fasteners—ideal for indoor and outdoor use, including high-moisture and chemically treated environments.
