All-Thread Rod, Grade 55\u003c\/strong\u003e is a fully threaded steel tension transfer element engineered for structural systems designed to resist seismic and wind forces. Built from uncoated black steel meeting ASTM A36 specifications with a minimum yield strength of 55 ksi and tensile strength of 75 ksi, this precut all-thread rod delivers a continuous and reliable load path from roof to foundation - making it an essential component in continuous rod tiedown systems, shearwall overturning restraint assemblies, and uplift restraint systems for roofs. Its UNC Class 2A thread specification and fully threaded design also make it suitable for use as an adhesive anchor rod in a wide range of structural and non-structural applications.\u003c\/p\u003e\n\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut 30 in. length\u003c\/strong\u003e - arrives ready to install without field cutting, saving labor time and reducing measurement error on the job site.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade 55 specification (ASTM A36;
