Machined from steel with a zinc-plated finish for corrosion resistance, this hex coupling nut features a 1\/4-20 UNC right-hand thread and measures 7\/8 inch overall length with 3\/8 inch width across flats. Grade 2 material meets standard load requirements for general mechanical assemblies. Electricians, HVAC techs, plumbers, and general trades use coupling nuts when extending threaded rod, mounting equipment, or joining all-thread in panel and bracket installations.\u003c\/p\u003e\n\u003cp\u003eThis coupling nut is suited for light- to medium-duty fastening applications across residential and commercial trade work. Common uses include threaded rod extensions in electrical conduit support, HVAC equipment mounting, pipe hanger assemblies, and general structural bracketing. The 1\/4-20 UNC thread is one of the most widely used coarse-thread standards in North American trade applications, making this nut broadly useful across fastener inventories.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC coarse right-hand thread for broad compatibility with standard fasteners\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel finish provides basic corrosion protection in indoor and sheltered environments\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch overall length allows rod extension or joining in tight clearance situations\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch width across flats fits standard hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets general-purpose mechanical load requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC coupling nut for use with any Grade 2 or equivalent 1\/4-20 UNC threaded rod, bolt, or stud conforming to standard coarse-thread specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard hex wrench or socket sized to 3\/8 inch across flats. Ensure mating threaded components are clean and free of debris before threading to avoid cross-threading or galling. De-energize and lock out any electrical or mechanical system before installing fasteners in live panels or moving equipment. Do not exceed the load rating of Grade 2 hardware in structural or high-vibration applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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 (OAL)\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/8 inch\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: 0.05 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: 250039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705742426418,"sku":"250039","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e636235f99d83ca599312c99b961edc2.jpg?v=1788430852","url":"https:\/\/voomisupply.com\/products\/value-collection-250039-coupling-nut-1-4-20-unc-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
