All-Thread Rod, Grade 55\u003c\/strong\u003e is a fully threaded steel rod engineered as a tension transfer element for structural systems designed to resist seismic and wind forces. Built to deliver a continuous and reliable load path from roof to foundation, this precut threaded rod is a core component in continuous rod tiedown systems for shearwall overturning restraint and in uplift restraint systems for roof applications. Its fully threaded profile also makes it suitable for use as an adhesive anchor rod in a variety of structural and construction contexts.\u003c\/p\u003e\n\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut 12 in. length\u003c\/strong\u003e - ready to install without field cutting, saving time and reducing jobsite waste during structural assembly.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade 55 specification (ASTM A36;
