All-Thread Rod, Grade 55\u003c\/strong\u003e is a fully threaded structural steel rod engineered as a tension transfer element for systems designed to resist seismic and wind forces. Built from uncoated ASTM A36 black steel with a minimum yield strength of 55 ksi, this all-thread rod provides a continuous and reliable load path from roof to foundation - making it a trusted component in shearwall overturning restraint applications and uplift restraint systems for roofs. Its fully threaded design also makes it suitable for use as an adhesive anchor rod and a range of other structural fastening applications.\u003c\/p\u003e\n\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut 48 in. length\u003c\/strong\u003e - ready to install right out of the box, saving time on the job site without the need for cutting or measuring\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMeets Grade 55 specifications (ASTM A36; Fy = 55 ksi and Fu = 75 ksi)\u003c\/strong\u003e - delivers the tensile strength required for engineered structural tiedown and uplift restraint systems\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUNC Class 2A thread specification\u003c\/strong\u003e - ensures consistent, reliable thread engagement with compatible nuts and couplers used in continuous rod tiedown assemblies\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e7\/8 in. rod diameter\u003c\/strong\u003e - sized for use in strong-rod systems where a larger-diameter rod is needed to handle greater structural loads\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUncoated black steel construction\u003c\/strong\u003e - provides a clean, bare steel surface compatible with a variety of structural system components and adhesive anchor installations\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFully threaded along the entire length\u003c\/strong\u003e - allows connection points at any location along the rod, giving installers maximum flexibility in positioning hardware within a load path assembly\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-resisting structural systems, this all-thread rod supports continuous load path construction from roof to foundation - a critical requirement in high-wind and seismic design zones.\u003c\/li\u003e\n \u003cli\u003eThe precut 48 in. length eliminates field cutting, reducing installation time and helping ensure consistent rod lengths across a tiedown system installation.\u003c\/li\u003e\n \u003cli\u003eGrade 55 steel with ASTM A36 certification means this threaded rod meets recognized engineering specifications, supporting use in engineered shearwall overturning restraint and roof uplift restraint designs.\u003c\/li\u003e\n \u003cli\u003eThe fully threaded profile makes this rod equally suited for use as an adhesive anchor rod, giving structural contractors a single versatile component that works across multiple application types on the same job.\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 ATRM7-4\u003c\/li\u003e\n\n \u003cli\u003e\n\u003cstrong\u003eRod Diameter:\u003c\/strong\u003e 7\/8 in.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eRod Length:\u003c\/strong\u003e 48 in.\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\u003eMaterial Standard:\u003c\/strong\u003e ASTM A36; Fy = 55 ksi and Fu = 75 ksi\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\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 roofs\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 is this all-thread rod used for in structural construction?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eThis fully threaded rod is used as a tension transfer element in structural systems designed to resist seismic and wind forces.
