Rated to a safe working load of 12,000 lbs and manufactured to ASTM A307 Grade A standards, this rod delivers the structural reliability that plumbing, HVAC, and electrical trades require. The coarse UNC thread pattern resists cross-threading and speeds installation when paired with standard hex nuts and couplings. The full 72-inch length allows field cutting to exact dimensions as the job demands.\u003c\/p\u003e\u003cp\u003eThis threaded rod is suited for interior residential and light commercial installations where hanging and support work is required. Common applications include pipe hanger assemblies, electrical conduit supports, HVAC duct and equipment mounting, and structural clamping in mechanical rooms. Because it can be drilled, cut, heated, or shaped in the field, it adapts to a wide range of fastening scenarios without requiring pre-fabricated lengths. It ships as a single 72-inch rod ready for immediate use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSafe working load of 12,000 lbs for heavy-duty hanging and support tasks\u003c\/li\u003e\n\u003cli\u003eMeets ASTM A307 Grade A specification for carbon steel externally threaded fasteners\u003c\/li\u003e\n\u003cli\u003e1 inch-8 UNC coarse thread for fast engagement with standard hardware\u003c\/li\u003e\n\u003cli\u003e72-inch length can be field-cut, drilled, heated, or shaped to fit the installation\u003c\/li\u003e\n\u003cli\u003eSuitable for plumbing, HVAC, and electrical support applications\u003c\/li\u003e\n\u003cli\u003eInterior use designation — not rated for direct outdoor or corrosive exposure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1 inch-8 UNC threaded rod compatible with matching UNC hex nuts, coupling nuts, washers, and pipe hanger hardware used in residential and commercial interior mechanical installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC mechanics, or electricians depending on the application. Always de-energize electrical systems and isolate any pressurized lines before mounting support hardware nearby. Use appropriate thread lubricant or anti-seize on nut engagement for clamping assemblies that may require future adjustment. Cutting should be performed with a reciprocating saw or hacksaw, and cut ends should be deburred before threading nuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1 inch-8 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe Working Load\u003c\/strong\u003e: 12,000 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNC Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Interior\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A307 Grade A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.45 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NATIONAL MFG\/SPECTRUM BRANDS HHI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N179-663\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51558393610546,"sku":"N179-663","price":48.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20df73b293bf2bb97dcfc039718a6c4b_16e4dcaf-2bb6-4655-a5c6-ad2fbaa8cbbd.jpg?v=1786411064","url":"https:\/\/voomisupply.com\/products\/national-mfg-n179-663-steel-threaded-rod-1-8x72","provider":"Voomi Supply","version":"1.0","type":"link"}
