The rod features UNC coarse threads and meets ASTM A37 Grade A standards with a minimum tensile strength of 6 KSI. Its zinc finish provides basic corrosion resistance for indoor and light-duty applications. The full 36-inch length allows field technicians to cut the rod to the required length on site, and the material accommodates drilling, heating, and shaping as job conditions require. Sold in a package of 5 rods.\u003c\/p\u003e\u003cp\u003eThis threaded rod is suited for residential and light commercial mechanical and construction work. Common uses include mounting strut channel, supporting pipe hangers, anchoring equipment, and assembling custom fastener assemblies. The 1\/4-20 UNC thread pattern is a widely used standard size, compatible with matching hex nuts, coupling nuts, and other UNC-threaded hardware. Installers working on HVAC equipment hangers, plumbing support frames, or electrical conduit racks will find this rod length practical for a wide range of field cuts and configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC coarse thread pattern for broad hardware compatibility\u003c\/li\u003e\n\u003cli\u003e36-inch length allows field cutting to required dimensions\u003c\/li\u003e\n\u003cli\u003eZinc plating provides corrosion resistance for indoor applications\u003c\/li\u003e\n\u003cli\u003eMeets ASTM A37 Grade A specification with 6 KSI minimum tensile strength\u003c\/li\u003e\n\u003cli\u003eCan be drilled, cut, heated, and shaped on site\u003c\/li\u003e\n\u003cli\u003eSold as a package of 5 rods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/4-20 UNC hex nuts, coupling nuts, and threaded inserts in typical mechanical, plumbing, electrical, and HVAC support and hanging assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians, plumbers, or electricians depending on the application. Use appropriate thread-cutting or abrasive tools when sizing the rod to length, and deburr cut ends before threading hardware. Follow applicable mechanical and building codes, including NEC or IPC requirements, for supported system types. Avoid using this zinc-plated rod in wet or corrosive environments where stainless or hot-dip galvanized hardware is specified.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\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\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.75 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: N179-499\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51561644720434,"sku":"N179-499","price":15.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8db2913013507b9852db549089f365c_6d054fff-2436-473e-9498-954deae74c22.jpg?v=1786467015","url":"https:\/\/voomisupply.com\/products\/national-mfg-n179-499-threaded-rod-1-4-20-x-36-in-zinc-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
