Power Pro 1/4 in. x 3-1/4 in. Flat-Head Concrete Screw Anchors, 225-Pack

Power Pro 1/4 in. x 3-1/4 in. Flat-Head Concrete Screw Anchors, 225-Pack are the ultimate choice for fastening into concrete and masonry materials with confidence. These screw anchors are code-approved and designed to deliver exceptional performance. Featuring a durable epoxy coating, they provide superior, multi-layer corrosion resistance, making them ideal for treated lumber and outdoor applications. Tested to withstand over 1,500 hours of rigorous salt spray, these anchors meet various building code approvals, including ICC ES ratings for concrete, masonry, and chemically treated wood. The blue color of these anchors complements a variety of projects, while the epoxy coating offers 50 percent greater corrosion protection compared to competitor anchors. Made from heat-treated carbon steel, they ensure high material strength and durability. Their superior strength thread design includes wide, serrated threads that cut fast and clean into concrete, with mid-crossband threads for drive stability. Threaded to the tip, they penetrate and sink quickly into wood without the need for a chisel point. The flat head design is perfect for wood-to-concrete and countersunk hole applications, and under head micro-nibs help cut a clean countersink in wood. The six-point star drive spreads out torque to prevent stripping during installation. These anchors are approved by California and Florida building codes, with Miami-Dade County Product Control approval in process, and they are safe for use with AC257 treated lumber.
