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 from uncoated black steel to ASTM A36 material standards, this precut rod provides a continuous and reliable load path from roof to foundation - making it a trusted component in continuous rod tiedown systems for shearwall overturning restraint and in uplift restraint systems for roofs. It is also well-suited for use as an adhesive anchor rod and a variety of other structural anchoring applications.\u003c\/p\u003e\n\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut to 24 in. length\u003c\/strong\u003e - arrives ready to install with no cutting required, saving time and labor on the job site.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMeets Grade 55 specifications\u003c\/strong\u003e - delivers the tensile and yield strength needed for demanding seismic and wind-force applications in structural systems.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eASTM A36 material; Fy = 55 ksi and Fu = 75 ksi\u003c\/strong\u003e - independently verified steel properties ensure predictable, code-compliant structural performance.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUNC Class 2A thread specification\u003c\/strong\u003e - provides a standardized thread form that ensures reliable fitment with compatible nuts, couplers, and tiedown hardware.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUncoated black steel finish\u003c\/strong\u003e - a clean, bare-steel surface compatible with adhesive anchor systems and a wide range of structural connection methods.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e1 in. diameter rod\u003c\/strong\u003e - sized for high-load tension transfer applications including shearwall overturning restraint and roof uplift restraint systems.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eWhy This Product\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eDesigned specifically as a tension transfer element for seismic and wind-force resistance, this all-thread rod supports a continuous load path from roof to foundation - addressing one of the most critical requirements in shearwall and uplift restraint system design.\u003c\/li\u003e\n \u003cli\u003eThe precut 24 in. length eliminates field cutting and reduces installation time, giving contractors a job-site-ready component that maintains consistent dimensional accuracy.\u003c\/li\u003e\n \u003cli\u003eWith Grade 55 strength and ASTM A36 material certification, this threaded rod meets the structural requirements for use in engineered continuous rod tiedown systems without the uncertainty of uncertified alternatives.\u003c\/li\u003e\n \u003cli\u003eThe UNC Class 2A thread specification ensures compatibility with standard tiedown hardware and couplers, reducing the risk of mismatched fasteners and simplifying procurement.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eSpecifications\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Simpson Strong-Tie\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e ATRM8-2\u003c\/li\u003e\n\n \u003cli\u003e\n\u003cstrong\u003eRod Diameter:\u003c\/strong\u003e 1 in.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eRod Length:\u003c\/strong\u003e 24 in.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Uncoated Steel\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Uncoated Steel\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e Grade 55\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eThread Specification:\u003c\/strong\u003e UNC Class 2A\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eASTM Standard:\u003c\/strong\u003e ASTM A36; Fy = 55 ksi and Fu = 75 ksi\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eProduct Class:\u003c\/strong\u003e Threaded Rod\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eProp 65:\u003c\/strong\u003e No\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eApproved Applications\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003eContinuous rod tiedown systems for shearwall overturning restraint\u003c\/li\u003e\n \u003cli\u003eUplift restraint systems for roof applications\u003c\/li\u003e\n \u003cli\u003eAdhesive anchor rod applications\u003c\/li\u003e\n \u003cli\u003eStructural systems designed to resist seismic and wind forces\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n \u003cdl\u003e\n \u003cdt\u003e\u003cstrong\u003eWhat structural applications is this all-thread rod designed for?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eThis fully threaded rod is designed for use as a tension transfer element in structural systems that resist seismic and wind forces.
