It carries a 5\/8-18 UNF thread, a 2-inch length under head, and a 1-1\/2-inch thread length, leaving a smooth shank section between the flange and the threads. The integral flange — 1-21\/64 inches (1.3281 inches) in diameter — distributes clamping load across a wider surface area without a separate washer. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, this bolt delivers high tensile strength and moderate corrosion resistance. It is installed with a standard hex drive and meets IFI 111 and SAE J429 fastener standards.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for heavy-duty mechanical and structural assemblies where a flanged bearing surface eliminates the need for a flat washer and maintains consistent clamp load. Typical applications include automotive drivetrain components, agricultural equipment frames, industrial machinery, and fabricated steel structures. The partially threaded shank provides a grip area that resists shear loads at the joint interface, making it a preferred choice where alignment and shear strength matter alongside tensile clamping force.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF thread for fine-pitch engagement and precise clamp-load control\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 distributes load without a separate washer\u003c\/li\u003e\n  \u003cli\u003ePartial threading with 1-1\/2-inch thread length leaves a full-shank grip zone for shear resistance\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish provides moderate corrosion and galling resistance\u003c\/li\u003e\n  \u003cli\u003eMeets IFI 111 and SAE J429 fastener standards for dimensional and mechanical compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for assemblies requiring a 5\/8-18 UNF partially threaded smooth flange bolt with a 2-inch length under head and Grade 8 alloy steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a mechanic, millwright, or qualified tradesperson using a standard hex wrench or socket. Verify mating thread condition and clean threads before assembly. Apply torque per the applicable Grade 8 fastener torque specification for the joint design — do not substitute a lower-grade fastener in a Grade 8-rated joint. Follow applicable machinery safety lockout and tagout procedures before servicing any assembly that includes this fastener.\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\u003eThread Standard\u003c\/strong\u003e: 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 Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\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\u003eFlange Type\u003c\/strong\u003e: Smooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: Phosphate and Oil\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: 0.29 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 821088MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715923804466,"sku":"821088MSC","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/658b92310a41eb1231fc913bcd06023d.jpg?v=1788519781","url":"https:\/\/voomisupply.com\/products\/value-collection-821088msc-flange-bolt-5-8-18-unf-2in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
