Manufactured from steel with a zinc-plated finish, this fastener resists corrosion in typical indoor and light-duty service environments. The 5\/8-11 unified coarse right-hand thread and 2.125-inch overall length make it a straightforward component for structural connections, hanging applications, and threaded rod assemblies. Electricians, plumbers, HVAC techs, and general contractors reach for coupling nuts when extending all-thread rod in suspended ceiling grids, pipe hangers, equipment mounts, and similar trade installations.\u003c\/p\u003e\n\u003cp\u003eThis coupling nut is suited for light commercial and residential trade applications wherever 5\/8-11 threaded rod or hardware requires extension or joining. Typical uses include mechanical system hangers, unistrut assemblies, equipment support rods, and general fastening tasks that call for a standard unified coarse hex coupling nut. The zinc-plated finish is appropriate for dry or mildly humid indoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 unified coarse right-hand thread for broad hardware compatibility\u003c\/li\u003e\n  \u003cli\u003e2.125-inch overall length provides sufficient engagement for secure rod-to-rod joining\u003c\/li\u003e\n  \u003cli\u003eSteel construction delivers solid tensile strength for structural hanging and support tasks\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish adds corrosion resistance for indoor and light-duty service conditions\u003c\/li\u003e\n  \u003cli\u003eCompact weight of 0.18 pounds keeps assembly weight low in overhead installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 coarse-thread coupling nut compatible with any 5\/8-11 threaded rod, bolt, or stud conforming to unified coarse thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools beyond a wrench sized for the hex flats of the coupling nut. Verify that mating threaded rod or fasteners share the same 5\/8-11 coarse thread specification and right-hand thread direction before assembly. Ensure adequate thread engagement on both ends of the nut for full load-bearing capacity. For overhead or structural applications, follow applicable building codes and load rating guidelines for the full fastener assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 Unified Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EMPIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51G0058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMPIRE INDUSTRIES","offers":[{"title":"Default Title","offer_id":51695364145458,"sku":"51G0058","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9e2a36a7731b64196254ef98873516f.jpg?v=1788334259","url":"https:\/\/voomisupply.com\/products\/empire-51g0058-coupling-nut-5-8-11-thread-zinc-plated-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
