Machined from steel with a zinc-plated finish for basic corrosion resistance, this hex coupling nut measures 1-3\/4 inches overall length (OAL) with 11\/16 inches across the flats. It carries a Material Grade 2 designation, making it suitable for general-purpose mechanical and structural fastening applications. The right-hand thread direction follows standard UNC convention. Licensed tradespeople, maintenance mechanics, and fabricators reach for this part when extending threaded connections or anchoring hardware to structural members.\u003c\/p\u003e\n\u003cp\u003eThis coupling nut is used in a wide range of residential, commercial, and industrial fastening scenarios. Common applications include threaded rod extensions in HVAC hangers and pipe support assemblies, electrical conduit support strut work, plumbing pipe hanger rods, and general structural fabrication. The 1\/2-13 UNC thread is one of the most common coarse-thread sizes in North American trade work, so this nut sees frequent use wherever threaded rod needs to be lengthened or two male-threaded fasteners need to be joined end to end.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread, right-hand direction — matches the most common threaded rod and bolt standard in North American trade applications\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inches OAL provides generous thread engagement for secure load transfer\u003c\/li\u003e\n  \u003cli\u003e11\/16 inches width across flats — fits standard open-end, box, and socket wrenches\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel finish offers baseline corrosion protection for interior and dry-location use\u003c\/li\u003e\n  \u003cli\u003eMaterial Grade 2 steel construction for general-purpose mechanical fastening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC coupling nut compatible with any male-threaded fastener, bolt, or threaded rod conforming to the UNC 1\/2-13 thread standard.

Verify that mating threaded rod or fasteners are clean, undamaged, and of matching UNC thread class before assembling. De-energize or depressurize any system before disturbing hanger rod assemblies supporting mechanical or electrical equipment. For structural or load-bearing hanger applications, follow applicable code requirements including ASCE 7 loading criteria and local mechanical or building codes.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 11\/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: 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: 0.01 pounds\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: 36673\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692844679474,"sku":"36673","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6de40d5bd8be007f2272622ed8c544c.jpg?v=1788303935","url":"https:\/\/voomisupply.com\/products\/value-collection-36673-coupling-nut-1-2-13-unc-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
