This fastener features two different thread pitches on a single shank — a 3\/8-16 (UNC) short end and a 3\/8-24 (UNF) long end — allowing it to bridge applications where coarse and fine thread interfaces must mate. The overall length is 1.5 inches, with a short thread length of 0.5 inches, a long thread length of 0.75 inches, and an unthreaded shank of 0.25 inches. Sold in a pack of 25, this stud is suited for mechanical assembly, HVAC equipment mounting, and other trade fastening applications requiring mixed-thread engagement.\u003c\/p\u003e\n\u003cp\u003eUnequal double threaded studs are used in residential and commercial mechanical systems where a permanent or semi-permanent threaded connection is needed between two components with dissimilar thread standards. Common applications include equipment mounting, manifold assembly, and structural fastening in HVAC, plumbing, and general mechanical trade work. The Grade 8 material rating indicates high tensile strength suitable for moderate-to-high load fastening environments. The yellow zinc dichromate finish provides corrosion resistance appropriate for indoor mechanical environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUnequal thread configuration: 3\/8-16 UNC short end and 3\/8-24 UNF long end on a single stud\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eYellow zinc dichromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.5 inches with 0.25-inch unthreaded shank between thread zones\u003c\/li\u003e\n  \u003cli\u003eNo flat — designed for direct thread-driven installation\u003c\/li\u003e\n  \u003cli\u003eSold in a convenient pack of 25 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-inch unequal double threaded stud for general mechanical fastening applications requiring both UNC and UNF thread engagement in a single fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed mechanic, HVAC technician, or plumber using a stud driver or appropriately sized hex socket. Power down and de-energize any equipment before fastener service. Ensure mating threads are clean and free of debris before engagement. Do not cross-thread; the short end (3\/8-16 coarse) and long end (3\/8-24 fine) are not interchangeable and must be oriented to match the correct receiving thread.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShort Thread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLong Thread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnthreaded Shank Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShort-End Thread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLong-End Thread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Unequal Double Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlat\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Yellow Zinc Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161618\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: 36965\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698094309682,"sku":"36965","price":109.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82153aa70323e333c9d2e115dc9c3602.jpg?v=1788357662","url":"https:\/\/voomisupply.com\/products\/value-collection-36965-unequal-double-threaded-stud-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
