Power Pro 376641 Concrete Screw Anchors, 1/4" x 2-3/4", High-Performance, Code-Approved, Epoxy Coated, Coarse Thread, for Concrete and Masonry, Outdoor Rust Resistant, #410 Stainless Flat, 100pcs

Power Pro Flat-Head Concrete Screw Anchors are the best performing code-approved screw anchor for fastening into concrete and masonry materials. The durable epoxy coating provides superior, multi-layer corrosion protection in treated lumber and outdoor applications. These screw anchors also surpass 1,500 of rigorous salt spray testing and carry various building code approvals and listings. These durable, corrosion-resistant anchors are ICC-ES Code Compliant for concrete, masonry, and chemically treated wood and are available in three colors, blue, white, and black in various lengths and 3/16”, 1/4”, and 5/16” diameters. Unlike competitor anchors, the Power Pro Concrete Screw Anchors feature a fully threaded tip, instead of a chisel point, to quickly penetrate and sink into wood. The under head micro-nibs help flat head screws cut a clean countersink in wood. With 25% higher pullout rate, 5% higher shear value and 50% greater corrosion protection, this is the only concrete fastener pros and DIYers will ever need.
