The coupling measures 7\/8 inches in length with a 3\/8-inch outer diameter and is manufactured from steel with a zinc finish for corrosion resistance. These small-diameter couplings are a standard fastener for trade installations where all-thread rod must be extended or connected to a compatible threaded fitting. Licensed electricians, plumbers, and mechanical contractors regularly use rod couplings when building pipe hangers, equipment supports, and conduit strut systems.\u003c\/p\u003e\u003cp\u003eThe 25RC is suited for light-duty support and hanger assemblies in residential and commercial mechanical systems. Common applications include suspending pipe hangers, HVAC equipment, conduit supports, and plumbing fixture brackets from structural overhead surfaces. The 1\/4-20 thread pitch is widely used in smaller-diameter rod hanger configurations where load requirements fall within the capacity of this thread size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 unified coarse thread for broad compatibility with standard all-thread rod stock\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc finish for basic corrosion protection in indoor applications\u003c\/li\u003e\n\u003cli\u003e7\/8-inch body length for compact inline rod extension\u003c\/li\u003e\n\u003cli\u003e3\/8-inch outer diameter for use in tight hanger and support assemblies\u003c\/li\u003e\n\u003cli\u003eStandard hex-drive form allows installation with common hand tools or a socket wrench\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or supplemental fastener for 1\/4-20 threaded rod assemblies used in mechanical, plumbing, and electrical support systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eRod couplings are installed by threading onto compatible 1\/4-20 all-thread rod using an appropriately sized wrench or socket. Ensure both mating rods are fully engaged within the coupling body before applying load. Support assemblies should comply with applicable building, mechanical, or electrical codes such as the NEC or IPC for hanger spacing and load ratings. Do not use zinc-plated steel couplings in outdoor or high-moisture environments where more corrosion-resistant materials are required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 3\/8 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662352366847\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STEWART FASTENER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 25RC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STEWART FASTENER","offers":[{"title":"Default Title","offer_id":51383744102706,"sku":"25RC","price":30.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671849.jpg?v=1782606092","url":"https:\/\/voomisupply.com\/products\/stewart-fastener-25rc-1-4-20-rod-coupling-steel-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
