Hillman 3/16" x 2-3/4" Power Pro Flat-Head Concrete Screw Anchors, 225-Pack

Hillman 3/16" x 2-3/4" Power Pro 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 deliver exceptional performance thanks to their durable epoxy coating, which provides superior multi-layer corrosion resistance, making them perfect for treated lumber and outdoor applications. Tested to withstand over 1,500 hours of rigorous salt spray, they meet various building code approvals, including ICC ES ratings for concrete, masonry, and chemically treated wood. Featuring a striking blue color that complements many projects, these anchors are crafted from heat-treated carbon steel for outstanding strength and durability. Their wide, serrated threads cut quickly and cleanly into concrete, while mid-crossband threads ensure drive stability. The threading extends to the tip for fast penetration into wood without the need for a chisel point. The flat head design is ideal for wood-to-concrete and countersunk hole applications, enhanced by under-head micro-nibs that create a clean countersink in wood. A star drive with six contact points spreads torque evenly to prevent stripping during installation. These anchors are also safe for use with treated lumber, being AC257 Treated Lumber approved, and are in the process of receiving additional approvals from Florida and Miami-Dade County building codes.
