Manufactured from Grade 8 alloy steel with a phosphate and oil finish, this bolt provides corrosion resistance and reliable clamping force in demanding mechanical and structural assemblies. The 5\/8-11 UNC thread and 4-1\/2-inch length under head make it suited for heavy-duty bolted connections. The partial threading leaves a shank section for shear-load applications. Licensed trades and industrial maintenance professionals install this type of fastener in equipment, structural steel, and machinery mounting work.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is appropriate for use in industrial, commercial, and trade maintenance applications where a smooth flange distributes load across a wider bearing area without the need for a separate washer. The hex drive allows installation with standard 6-point sockets or wrenches. The 1-21\/64-inch flange diameter and 1-1\/2-inch thread length are typical specifications for medium-to-large fastener assemblies in HVAC equipment mounting, mechanical rooms, and structural connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eSmooth flange eliminates the need for a separate flat washer in most applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC partially threaded shank supports shear and tensile loads\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish provides baseline corrosion and galling resistance\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard sockets and combination 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 an OEM-style replacement or maintenance fastener for applications requiring a 5\/8-11 UNC smooth flange bolt with a 4-1\/2-inch length under head and Grade 8 alloy steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or licensed trade professional familiar with fastener torque requirements for Grade 8 hardware. Always de-energize and lock out equipment before replacing or tightening fasteners on mechanical assemblies. Use a calibrated torque wrench and follow the torque specification table for 5\/8-11 UNC Grade 8 bolts as published by the fastener manufacturer or applicable equipment service manual. Inspect threads and mating surfaces for damage before installation.\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: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 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: 0.49 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: 822811MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695778627890,"sku":"822811MSC","price":16.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77c8c6b1b69f078db43204a63b376ad2_4f6ab3d7-eedf-4120-9257-905abfb7bf64.jpg?v=1788338167","url":"https:\/\/voomisupply.com\/products\/value-collection-822811msc-flange-bolt-5-8-11-unc-4-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
