Sized for 5\/8-inch diameter rod with 11 threads per inch (UNC coarse thread), this coupler provides a secure mechanical connection in suspended-load and structural applications. Witness holes on the coupler body allow the installer to confirm that both rods are fully threaded into the fitting before load is applied. Sold in a package of 15 units, this coupler is a standard component for licensed electricians, plumbers, HVAC technicians, and general contractors working with threaded rod hanger systems.\u003c\/p\u003e\u003cp\u003eThis coupler is used wherever threaded rod extensions are needed — suspended ceiling grids, pipe hanger systems, equipment supports, unistrut assemblies, and mechanical room overhead structure. The 5\/8-11 UNC sizing is common in medium-to-heavy-duty commercial and industrial installations. The zinc finish provides basic corrosion resistance suitable for interior applications. Each package contains 15 couplers, making it practical for multi-point hanger runs or stocking a service vehicle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eConnects two pieces of 5\/8-inch diameter, 11 TPI UNC threaded rod end-to-end\u003c\/li\u003e\n\u003cli\u003eWitness holes confirm full rod engagement before loading\u003c\/li\u003e\n\u003cli\u003eZinc construction provides corrosion resistance for interior use\u003c\/li\u003e\n\u003cli\u003eUNC coarse thread sizing for broad compatibility with standard threaded rod stock\u003c\/li\u003e\n\u003cli\u003eSold in a 15-unit package for multi-point installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style mechanical connector for standard 5\/8-11 UNC threaded rod used in commercial and residential hanger and support applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed tradespeople or qualified contractors working with threaded rod support systems. Thread both rod ends fully into the coupler until visible through the witness holes before applying any load. Follow applicable building codes and engineering load ratings for the specific hanger or support system in use. Do not use in applications requiring corrosion resistance beyond what zinc plating provides without verifying suitability for the environment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNC Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 15 units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.05 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: N182-717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NATIONAL HARDWARE","offers":[{"title":"Default Title","offer_id":51560893251890,"sku":"N182-717","price":71.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ec9cd36db8bc9753ab94148b52066ff_2d89ca08-f1d0-4022-999b-626391cf4509.jpg?v=1786459208","url":"https:\/\/voomisupply.com\/products\/national-mfg-n182-717-threaded-rod-coupler-5-8-11-zinc-15-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
