It features a 5\/8-11 UNC thread form and is fully threaded along its 1-1\/2 inch length under head, giving maximum thread engagement in blind or through-hole assemblies. The integrated smooth flange measures 1-21\/64 inches (1.3281 inches) in diameter and distributes clamping load evenly across the joint surface. Constructed from Grade 8 alloy steel with a zinc yellow dichromate finish, this bolt delivers high tensile strength and corrosion resistance in demanding mechanical and structural environments. It is used by maintenance professionals, millwrights, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is suited for heavy equipment assembly, industrial machinery, automotive drivetrain components, and structural steel connections where Grade 8 strength is specified. The hex drive accepts standard hex wrenches and impact sockets. The zinc yellow dichromate coating provides moderate corrosion protection and meets IFI 111 and SAE J429 standards. It is sold individually but requires a minimum order quantity of 25 pieces per order, making it appropriate for shop stock and maintenance parts inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC fully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003eSmooth integral flange at 1-21\/64 inches diameter eliminates the need for a separate flat washer\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003eMeets IFI 111 and SAE J429 fastener standards\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard wrenches and impact tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 UNC smooth flange bolt for use in any application specifying a Grade 8 alloy steel hex flange fastener to IFI 111 or SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanics, millwrights, or maintenance technicians using standard hex wrenches or impact sockets sized for 5\/8-inch hex drive fasteners. Always confirm the mating thread is clean, undamaged, and matches the 5\/8-11 UNC specification before installation. Apply torque to the Grade 8 rating specified in the applicable engineering drawing or fastener standard — do not substitute torque values from lower-grade hardware. Inspect the flange bearing surface and mating material for damage or debris before final torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Fully 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: 1-21\/64 inches (1.3281 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: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: IFI 111, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 47147\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718056739122,"sku":"47147","price":90.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b22ec18cea5cc1d361b10f3fb68c062c.jpg?v=1788549111","url":"https:\/\/voomisupply.com\/products\/value-collection-47147-flange-bolt-5-8-11-unc-1-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
