All-Thread Rod, Grade 55\u003c\/strong\u003e is a fully threaded structural steel rod engineered to serve as a tension transfer element within systems designed to resist seismic and wind forces. Built from uncoated black steel meeting ASTM A36 material standards, this all-thread rod delivers a continuous and reliable load path from roof to foundation - making it a trusted choice for contractors and structural engineers working on shearwall overturning restraint, uplift restraint systems for roofs, and adhesive anchor rod applications. Precut to a convenient 24-inch length and threaded its entire length, the rod integrates directly into continuous rod tiedown systems without modification, saving time on the jobsite.\u003c\/p\u003e\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut 24 in. length\u003c\/strong\u003e - arrives ready to install with no cutting required, reducing labor time and material waste on the jobsite.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade 55 specification\u003c\/strong\u003e - meets the strength demands of structural seismic and wind-force-resisting systems, providing engineered confidence in high-load applications.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUNC Class 2A thread specification\u003c\/strong\u003e - ensures compatibility with standard threaded connectors, couplers, and hardware used in continuous rod tiedown and uplift restraint systems.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eASTM A36;
