Check Markings. Never Rely on Imitations.<\/h2>\n<p>Structural retaining stars\u2014common on historic masonry buildings\u2014were originally engineered to provide critical reinforcement. But with age, many of these early stars, especially those made from low-grade cast iron, have become brittle and unreliable. Today, the market is flooded with decorative imitations that look the part but are <em>not<\/em> designed for load-bearing or structural use. These should <em>never<\/em> be installed where strength and safety are required.<\/p>\n<p>Our <strong>Structural Star Building Retaining Washers<\/strong> are proudly <strong>Made in the USA<\/strong> and built to exceed performance expectations. Also known as <strong>Seismic Earthquake Washers<\/strong> or <strong>Century Star Washers<\/strong>, they feature historically accurate architecture and function as anchor plates or wall washers for exterior masonry applications. When paired with tie rods or bolts, these stars brace masonry walls, prevent lateral movement, and provide long-lasting structural stability. Available in both <strong>five- and six-point<\/strong> configurations, each star is produced in <strong>hot-galvanized cast ductile iron<\/strong>, with custom options available in aluminum or bronze.<\/p>\n<p><strong>Why Our Structural Stars Stand Apart<\/strong><br \/>\nManufactured from <strong>Ductile Iron, ASTM 65-45-12<\/strong>, our stars deliver near \u201csemi-steel\u201d strength and superior weldability. Unlike standard cast iron\u2014which can crack, fail, or break under stress\u2014our stars are engineered specifically for demanding structural roles and are <strong>hot-galvanized<\/strong> for unmatched durability in the field.<\/p>\n<p>You may also see these stars referenced as <strong>Gib Plates, Hurricane Bolts, Pattress Plates, Masonry Restraints,<\/strong> or <strong>Tie Backs<\/strong> in architectural and engineering plans. We also supply all required complementary hardware\u2014rods, nuts, washers, plates, turnbuckles\u2014to ensure a complete, reliable installation.<\/p>\n<p><strong>Quick Specs:<\/strong><\/p>\n<ul>\n<li>Most sizes feature a <strong>flat back<\/strong> with a <strong>7\/8&#8243; ID<\/strong>.<\/li>\n<li>Recommended hot-galvanized accessories: <strong>3\/4 Ogee Washer, 3\/4 USS Flat Washer, 3\/4-10 Heavy Hex Nut<\/strong>, and <strong>3\/4-10 \u00d7 6&#8242; Threaded Rod<\/strong>.<\/li>\n<li>Our 13&#8243; stars use <strong>1&#8243; hardware<\/strong> and measure <strong>2-1\/2&#8243;<\/strong> thick.<\/li>\n<li>All other sizes feature a standard <strong>7\/8&#8243;<\/strong> thickness.<\/li>\n<li>Popular sizes include our <strong>7-1\/2&#8243; (5-point)<\/strong>, with additional models ranging from <strong>5-1\/2&#8243;<\/strong> up to <strong>13&#8243;<\/strong>.<\/li>\n<\/ul>\n<p><strong>Bottom Line:<\/strong> Not all stars are built for structural reinforcement.
