The rod measures 1\/2-13 x 12 inches, featuring UNC coarse threads along its full length. It meets ASTM A37 Grade A standards with a minimum tensile strength of 6 KSI and a safe working load (SWL) of 3,100 pounds. The zinc finish provides corrosion resistance suitable for a range of indoor and light-duty applications. Sold in a package of 5 rods, it offers practical inventory for service contractors and installers who need ready stock on hand.\u003c\/p\u003e\u003cp\u003eThis threaded rod is suited for residential and light commercial installations where a standard 1\/2-13 UNC fastening solution is required. Common applications include suspending HVAC ductwork, securing pipe hangers, anchoring strut channel, and general structural fastening tasks. The rod can be drilled, cut, heated, or shaped in the field, giving installers flexibility to adapt the length and form to fit specific job conditions without additional tooling beyond what is typically on a service vehicle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFull-length UNC coarse threads for compatibility with standard 1\/2-13 nuts and couplings\u003c\/li\u003e\n\u003cli\u003eZinc finish for corrosion resistance in light-duty environments\u003c\/li\u003e\n\u003cli\u003eMeets ASTM A37 Grade A material standard\u003c\/li\u003e\n\u003cli\u003eMinimum tensile strength of 6 KSI with a safe working load of 3,100 pounds\u003c\/li\u003e\n\u003cli\u003eField-workable: can be drilled, cut, heated, or shaped on site\u003c\/li\u003e\n\u003cli\u003eSold in a package of 5 for efficient job-site supply\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-13 UNC threaded rod for use with compatible nuts, couplings, pipe hangers, and strut hardware in residential and light commercial fastening applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians, plumbers, or general contractors depending on the application. Always confirm that the anchoring substrate and associated hardware are rated to meet or exceed the SWL of 3,100 pounds before loading. When cutting the rod to length, use appropriate thread-chasing tools or a die to clean the cut end before threading on hardware. Follow applicable building codes, including IPC or IFGC guidelines where pipe or duct support is involved.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\/Finish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A37 Grade A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Tensile Strength\u003c\/strong\u003e: 6 KSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe Working Load (SWL)\u003c\/strong\u003e: 3,100 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 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: N179-358\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51562553803058,"sku":"N179-358","price":17.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8db2913013507b9852db549089f365c_0b677218-7151-41cb-a7b1-6fc532e6c39c.jpg?v=1786479588","url":"https:\/\/voomisupply.com\/products\/national-mfg-n179-358-zinc-threaded-rod-1-2-13-x-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
