It bridges a 1\/2-13 thread on one end to a 5\/8-11 UNC thread on the other, with a 1-1\/4 inch overall length. Constructed from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this coupling nut suits mechanical and structural fastening applications where rod-to-rod or rod-to-stud joining is required. It weighs 0.8 pounds and features a right-hand thread direction on both ends.\u003c\/p\u003e\n\u003cp\u003eThis coupling nut is used in light structural, mechanical, and general-purpose fastening assemblies. It is commonly installed by HVAC technicians, plumbers, electricians, and general contractors when extending threaded rod, anchoring equipment, or tensioning all-thread in suspended or surface-mounted installations. The 3\/16 inch width across flats is appropriate for a standard open-end or box wrench during installation and tightening.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing thread profile: 1\/2-13 on one end, 5\/8-11 UNC on the other\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch overall length for compact rod joining\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose mechanical use\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion protection\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction on both ends\u003c\/li\u003e\n  \u003cli\u003eISO 9001:2000 certified manufacturing standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard reducing coupling nut compatible with 1\/2-13 and 5\/8-11 UNC threaded rod, studs, or fasteners in general mechanical and structural fastening assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand-threading onto both mating threaded components before final tightening with an open-end or box wrench. Ensure both mating threads are clean and free of debris before engagement to avoid cross-threading. Do not exceed the load rating appropriate for Grade 2 steel fasteners in the intended application. Consult applicable structural or mechanical codes for torque and load requirements on your specific assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 x 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\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: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2000 Certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161728\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 250691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689356755250,"sku":"250691","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6907821c2a9c321a0c773ed8579312e5_c8cf6924-90ce-44be-99a8-3c0db7c07fd8.jpg?v=1788258176","url":"https:\/\/voomisupply.com\/products\/value-collection-250691-coupling-nut-1-2-13-x-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
