Built from Grade 8 alloy steel in an uncoated finish, this bolt delivers the tensile strength required in demanding service environments. The smooth flange bearing surface distributes clamping load across a wider area than a standard hex bolt head, reducing the need for a separate washer. The hex drive allows installation with standard hex tools. Thread size is 3\/4-16 UNF with a length under head of 3 inches and a thread length of 1.75 inches, leaving a smooth shank section between the flange and the threaded portion.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is suited for heavy equipment, machinery frames, engine mounts, and fabricated structural connections where a unified fine thread (UNF) pattern is specified. The partially threaded configuration positions the unthreaded shank across the shear plane of the joint, which is common practice in load-bearing connections. It is installed by machinists, maintenance technicians, millwrights, and field service mechanics working to IFI 111 and SAE J429 standards. Applications span automotive, agricultural, and general industrial use where Grade 8 strength is the minimum acceptable specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction meets IFI 111 and SAE J429 strength requirements\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 UNF thread for fine-thread engagement with higher clamp load per turn\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank — thread length 1.75 inches, smooth shank spans the grip zone\u003c\/li\u003e\n  \u003cli\u003eSmooth flange diameter of 1.5938 inches (1-19\/32 inches) provides integrated bearing surface\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications where a specific post-treatment will be applied or where coating is not required\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard open-end, box-end, and socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard IFI 111 and SAE J429 Grade 8 partially threaded smooth flange bolt; fits any application calling for a 3\/4-16 UNF flange bolt with a 3-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using standard hex sockets or wrenches. Always verify that the mating nut or tapped hole is rated for the same thread class and strength grade before torquing. De-energize or lock out any equipment before accessing fastener locations on live machinery. Do not mix Grade 8 hardware with lower-grade nuts or threaded inserts, as the assembly strength will default to the weaker component.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.75 inches (1-3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Type\u003c\/strong\u003e: Smooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 1.5938 inches (1-19\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\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: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: IFI 111, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C39067-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693324501298,"sku":"C39067-7","price":57.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/147f83345dde4e997996c8c8982ef187.jpg?v=1788310649","url":"https:\/\/voomisupply.com\/products\/value-collection-c39067-7-smooth-flange-bolt-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
