Since 1901 National Hardware has provided high-quality builder's hardware that meets and exceeds the needs of discerning customers and consumers alike. They're manufactured from high strength steel with a zinc-plated finish to build strong structural connections and come pre-drilled for the appropriate screw or bolt size needed. Additionally, the WeatherGuard protection coating withstands harsh weather conditions and protects the hardware from premature failure. Corner braces come in a variety of sizes from 1/2 inch to 5 inch for any DIY application, including shelves, chests, screens, windows, furniture and more.
