All-Thread Rod, Grade 55\u003c\/strong\u003e is a fully threaded steel rod engineered by \u003cstrong\u003eSimpson Strong-Tie\u003c\/strong\u003e to serve as a tension transfer element in structural systems designed to resist seismic and wind forces. By providing 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 fully threaded design also makes it suitable for use as an adhesive anchor rod, giving structural engineers and contractors a versatile fastening solution across a range of demanding applications.\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 install, eliminating on-site cutting and saving time during structural assembly\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade 55 specification (ASTM A36;
