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

Hillman 1/4" x 1-3/4" Power Pro Flat-Head Concrete Screw Anchors, 225-Pack are the best performing code-approved screw anchors designed for fastening into concrete and masonry materials. These anchors feature a durable epoxy coating that provides superior, multi-layer corrosion resistance, making them ideal for treated lumber and outdoor applications. They have surpassed 1,500 hours of rigorous salt spray testing and carry various building code approvals and listings, including ICC ES ratings for concrete, masonry, and chemically treated wood. The blue color matches or complements various projects, while the epoxy coating offers 50 percent greater corrosion protection compared to competitor screw anchors. Manufactured from heat-treated carbon steel, these anchors deliver high material strength and durability. Their superior strength thread design includes wide, serrated threads that cut fast, easy, and clean into concrete, along with mid-crossband threads for drive stability. Threaded to the tip, they offer quick penetration and sinking into wood without the need for a chisel point. The flat head is perfect for wood-to-concrete and countersunk hole applications, and the under head micro-nibs help flat-head screws cut a clean countersink in wood. Featuring a star drive with six contact points, these anchors spread out torque for no-strip installs. They are building code approved, including California Building Code approval, with Florida Building Code approval and Miami-Dade County Product Control in process. Safe for use with treated lumber, these parts are AC257 Treated Lumber approved. Model Number: 377031
