All-Thread Rod, Grade 55\u003c\/strong\u003e is a fully threaded structural rod engineered to serve as a tension transfer element within systems designed to resist seismic and wind forces. Built from uncoated black steel meeting ASTM A36 standards with a minimum yield strength of 55 ksi and minimum tensile strength of 75 ksi, this all-thread rod delivers a continuous and reliable load path from roof to foundation - making it a trusted choice for shearwall overturning restraint, roof uplift restraint applications, and adhesive anchor rod installations. Precut to a convenient 24-inch length, it integrates directly into continuous rod tiedown systems and uplift restraint systems without additional cutting or preparation.\u003c\/p\u003e\n\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut 24 in. length\u003c\/strong\u003e -
