This medium-strength rating makes it appropriate for tension transfer applications in seismic and wind-force resistant structural systems, including shearwall overturning restraint and roof uplift restraint.\u003c\/dd\u003e\n\n \u003cdt\u003e\u003cstrong\u003eCan this threaded rod be used as an adhesive anchor rod?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eYes. In addition to its use in continuous rod tiedown systems and roof uplift restraint systems, the ATRM is designed to be compatible with adhesive anchor rod applications, making it a versatile component for various structural connection needs.\u003c\/dd\u003e\n\n \u003cdt\u003e\u003cstrong\u003eWhat does the UNC Class 2A thread specification mean for compatibility?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eUNC Class 2A is a standard external thread classification for Unified National Coarse threads. This means the ATRM7-1.5 is compatible with standard nuts, couplers, bearing plates, and other hardware that use UNC Class 2B internal threads - the typical mating specification used throughout continuous rod tiedown and structural anchor systems.\u003c\/dd\u003e\n\n \u003cdt\u003e\u003cstrong\u003eIs this rod fully threaded, and why does that matter for installation?\u003c\/strong\u003e\u003c\/dt\u003e\n \u003cdd\u003eYes, the ATRM is a fully threaded rod (all-thread rod), meaning threads run the entire 18 in. length. Full threading allows hardware such as nuts and couplers to be positioned anywhere along the rod without being limited to a specific threaded zone, providing greater flexibility when fitting components within a structural assembly.\u003c\/dd\u003e\n \u003c\/dl\u003e\n\u003c\/div\u003e","brand":"SIMPSON","offers":[{"title":"Default Title","offer_id":48085360345318,"sku":"ATRM7-1.5","price":10.88,"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-atrm7-15-atrm-7-8-in-x-18-in-all-thread-rod-grade-55","provider":"FactoryDirectSupply.com","version":"1.0","type":"link"}
