This is a standard unified national coarse thread tolerance class, which means it is compatible with the nuts, couplers, take-up devices, and other hardware components commonly used in continuous rod tiedown and shearwall overturning restraint systems. Using a standardized thread class reduces fit issues and simplifies hardware selection on the job site.\u003c\/dd\u003e\n \u003cdt\u003e\u003cstrong\u003eWhat does \"Grade 55\" mean for this all-thread rod?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eGrade 55 refers to the rod's minimum yield strength of 55 ksi (55,000 pounds per square inch), as defined by the ASTM A36 material standard. The rod also carries a minimum tensile (ultimate) strength of 75 ksi. These values define the rod's load-carrying capacity and are used by structural engineers when calculating performance within seismic and wind-force-resistant systems.\u003c\/dd\u003e\n \u003cdt\u003e\u003cstrong\u003eCan the ATRM5-1.5 be used as an adhesive anchor rod?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eYes. In addition to its primary role as a tension transfer element in continuous rod tiedown and uplift restraint systems, the ATRM5-1.5 can be used as an adhesive anchor rod. The fully threaded design along the entire 18-inch length supports consistent bond surface contact when used with structural adhesive anchor applications.\u003c\/dd\u003e\n \u003cdt\u003e\u003cstrong\u003eIs the uncoated black steel finish appropriate for all installation environments?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eThe ATRM5-1.5 features an uncoated black steel finish with no protective coating applied. This makes it best suited for interior structural applications where moisture exposure is not a concern. For installations in corrosive, wet, or exterior environments, consult the applicable project specifications and engineering requirements to determine whether a coated or stainless alternative is more appropriate.\u003c\/dd\u003e\n \u003c\/dl\u003e\n\u003c\/div\u003e","brand":"SIMPSON","offers":[{"title":"Default Title","offer_id":48085360279782,"sku":"ATRM5-1.5","price":4.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0398\/5188\/4705\/files\/ATRM_5-8.png?v=1785360272","url":"https:\/\/factorydirectsupply.com\/products\/simpson-atrm5-15-atrm-5-8-in-x-18-in-all-thread-rod-grade-55","provider":"FactoryDirectSupply.com","version":"1.0","type":"link"}
