Machined from 304 stainless steel with a right-hand 3\/8-16 thread and an overall length of 1-1\/8 inches, this coupling nut delivers corrosion resistance suitable for wet, chemical, or outdoor environments. The uncoated finish keeps the 304 alloy surface exposed for maximum material performance. It is a standard hardware component installed by HVAC technicians, plumbers, electricians, and general contractors wherever threaded rod extensions or stud connections are required.\u003c\/p\u003e\n\u003cp\u003eThis coupling nut is suited for light-duty to medium-duty fastening applications in residential and commercial construction, mechanical systems, and equipment mounting. Common uses include threaded rod extensions for pipe hangers, equipment support frames, ductwork hangers, and electrical conduit support. The 3\/8-16 coarse thread pitch is one of the most widely used sizes across trade applications, making this nut a practical stocking item for service vehicles and shop inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 right-hand thread for compatibility with standard coarse-thread fasteners\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch overall length provides adequate thread engagement for reliable load transfer\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves natural 304 alloy properties without added plating\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.04 pounds, easy to carry in bulk on service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any standard 3\/8-16 right-hand threaded rod, bolt, or stud conforming to unified coarse thread specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires only standard wrenches or sockets sized for the coupling nut flats. Always de-energize and de-pressurize any system before modifying threaded connections that support mechanical or electrical loads. Thread engagement on both ends should be even to distribute load correctly. Follow applicable mechanical codes, including IFGC or IPC where pipe hanger applications are involved.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: EMPIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51SS0038K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMPIRE INDUSTRIES","offers":[{"title":"Default Title","offer_id":51693099614514,"sku":"51SS0038K","price":16.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e77f713e7cd62d3730a072fa1c7f389.jpg?v=1788307312","url":"https:\/\/voomisupply.com\/products\/empire-51ss0038k-coupling-nut-3-8-16-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
