All-Thread Rod, Grade 55\u003c\/strong\u003e is a fully threaded steel rod engineered to serve as a tension transfer element in structural systems designed to resist seismic and wind forces. Built to deliver a continuous and reliable load path from roof to foundation, this all-thread rod is a critical component in continuous rod tiedown systems for shearwall overturning restraint and in uplift restraint systems for roof applications. Its versatility also makes it well suited for use as an adhesive anchor rod in a wide range of construction scenarios.\u003c\/p\u003e\n\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut to 12 in. length\u003c\/strong\u003e - ready to install right out of the box, saving time on the job site without the need for field cutting.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade 55 specification (ASTM A36;
