Built from Grade 8 alloy steel in an uncoated finish, this bolt meets IFI 111 and SAE J429 standards, making it appropriate for demanding load-bearing connections. The 5\/8-18 UNF thread provides fine-thread engagement suited to applications requiring precise clamping force and vibration resistance. The integrated smooth flange distributes load across a wider bearing surface, eliminating the need for a separate washer in many installations. Hex drive allows standard socket or wrench installation. This fastener is sold individually per package with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is used in general industrial maintenance, equipment assembly, and fabrication work where fine-thread fasteners are specified. The 2-inch length under head and 1-21\/64-inch flange diameter make it suitable for medium-thickness joint stacks in machinery frames, brackets, and structural steel connections. Machinists, millwrights, maintenance technicians, and fabricators commonly install this bolt type. Its Grade 8 rating suits applications subject to high tensile and shear loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength in demanding assemblies\u003c\/li\u003e\n  \u003cli\u003eSmooth flange distributes clamping load without a separate washer\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a bearing surface for shear applications\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard sockets and open-end wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets IFI 111 and SAE J429 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-18 UNF smooth flange bolt suitable for use in any application specifying a Grade 8 partially threaded hex flange fastener per IFI 111 or SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or maintenance personnel familiar with fastener torque specifications for Grade 8 hardware. Always verify joint stack thickness against the 2-inch length under head before installation to ensure adequate thread engagement. Apply torque per the applicable engineering specification or fastener torque chart for 5\/8-18 UNF Grade 8 fasteners. Inspect threads for damage and ensure mating threads are clean and free of debris before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\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: 1-21\/64 inches (1.3281 inches)\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: C39065\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711422169394,"sku":"C39065","price":49.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c36900c75d26cb7919c069c270966b5d.jpg?v=1788476471","url":"https:\/\/voomisupply.com\/products\/value-collection-c39065-flange-bolt-5-8-18-unf-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
