When strength, speed, and corrosion resistance matter most, the Power Pro 376542 Flat Head Concrete Screw Anchors deliver professional-grade performance for demanding concrete and masonry applications. Designed for secure fastening into concrete, brick, block, and treated lumber, these anchors are ideal for both indoor and outdoor use.

Engineered for Superior Performance

• Heat-treated carbon steel construction ensures maximum tensile strength and durability.
• Blue epoxy coating provides 50% greater corrosion resistance than standard zinc-plated fasteners—ideal for use in treated lumber and high-moisture environments.
• Flat head design allows for flush, countersunk installation—perfect for wood-to-concrete applications and clean finishes.

Fast, Clean, and Reliable Installation

• Wide, serrated threads cut quickly and cleanly into concrete and masonry, reducing installation time and effort.
• Mid-crossband threads enhance drive stability and reduce cam-out.
• Under-head micro nibs help create a clean countersink in wood for a flush finish.
