All-Thread Rod, Grade 55\u003c\/strong\u003e is a fully threaded structural 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 standards, this all-thread rod delivers a continuous and reliable load path from roof to foundation - making it a critical component in continuous rod tiedown systems for shearwall overturning restraint and uplift restraint systems for roofs. Its fully threaded design also makes it suitable for use as an adhesive anchor rod, giving engineers and contractors added flexibility across a range of structural applications.\u003c\/p\u003e\n\n \u003ch3\u003eKey Features\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003ePrecut to 36 in. length\u003c\/strong\u003e -

It is used in continuous rod tiedown systems for shearwall overturning restraint and in uplift restraint systems for roofs. It can also be used as an adhesive anchor rod in other applications.\u003c\/dd\u003e\n \u003cdt\u003e\u003cstrong\u003eWhat are the thread specifications for this rod?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eThe rod uses a UNC Class 2A thread specification, which is a standard unified coarse thread form compatible with nuts, couplers, and other hardware used in Strong-Rod systems and general structural assemblies.\u003c\/dd\u003e\n \u003cdt\u003e\u003cstrong\u003eWhat do Grade 55 and the ASTM A36 designation mean for this rod?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eGrade 55 refers to the rod meeting a minimum yield strength (Fy) of 55 ksi and an ultimate tensile strength (Fu) of 75 ksi per ASTM A36 standards. These values define the rod's structural load capacity and ensure it meets the requirements of engineered shearwall tiedown and uplift restraint designs.\u003c\/dd\u003e\n \u003cdt\u003e\u003cstrong\u003eIs the rod fully threaded along its entire length?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eYes. This is an all-thread rod, meaning it is fully threaded from end to end. The fully threaded profile allows bearing hardware, take-up devices, and couplers to be positioned at any point along the rod, which is important for flexible installation within continuous rod tiedown assemblies.\u003c\/dd\u003e\n \u003c\/dl\u003e\n\u003c\/div\u003e","brand":"SIMPSON","offers":[{"title":"Default Title","offer_id":48085361098982,"sku":"ATRM7-3","price":22.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0398\/5188\/4705\/files\/ATRM_7-8.png?v=1785360272","url":"https:\/\/factorydirectsupply.com\/products\/simpson-atrm7-3-atrm-7-8-in-x-36-in-all-thread-rod-grade-55","provider":"FactoryDirectSupply.com","version":"1.0","type":"link"}
