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. By providing a continuous and reliable load path from roof to foundation, this threaded rod is a core component in continuous rod tiedown systems for shearwall overturning restraint as well as uplift restraint systems for roofs. Its versatility also extends to use as an adhesive anchor rod, making it a practical choice for contractors and structural engineers who need a dependable, precut all-thread rod ready to install.\u003c\/p\u003e\n\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut 36 in. length\u003c\/strong\u003e - arrives ready to use without additional cutting, saving time on the job site and reducing material waste.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade 55 specification (ASTM A36;
