Machined from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this nut measures 7\/8 inches overall length with a 3\/8-inch width across flats. The 1\/4-28 UNF right-hand thread is a fine-pitch unified thread, providing tighter thread engagement and greater resistance to loosening under vibration compared to coarse-pitch alternatives. Electricians, HVAC technicians, plumbers, and general trade contractors use coupling nuts when extending threaded rod, connecting stud ends, or making inline threaded connections in light-duty mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis coupling nut is suited for light structural, mechanical, and trade fastening applications where a 1\/4-28 UNF fine thread is specified. Common uses include threaded rod extensions, equipment mounting, conduit support assemblies, and general hardware connections in residential and commercial installations. The zinc-plated finish provides adequate protection in dry or mildly humid indoor environments. The compact 7\/8-inch length makes it appropriate for confined-space installations where a longer coupling nut would interfere with adjacent components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine-pitch right-hand thread for secure engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides adequate strength for light-duty fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion protection in dry indoor environments\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch overall length suits confined-space and standard inline threaded connections\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch width across flats accepts standard combination or open-end wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any 1\/4-28 UNF right-hand threaded fastener, stud, or threaded rod conforming to unified fine thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard open-end or combination wrench sized for 3\/8-inch width across flats. Ensure both mating fasteners share the same 1\/4-28 UNF thread specification before assembly to avoid cross-threading. De-energize and de-pressurize any system before servicing components secured by this fastener. Do not exceed the load ratings appropriate for Grade 2 steel in structural or safety-critical connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\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: UNF\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\u003eOverall Length (OAL)\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/8 inches\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: 250358\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694669857074,"sku":"250358","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88c45440cd199aeaa70ea7552664ba50.jpg?v=1788326934","url":"https:\/\/voomisupply.com\/products\/value-collection-250358-coupling-nut-1-4-28-unf-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
