Sized at 5\/8-11 UNC with a 2-inch length under head, this partially threaded bolt is manufactured from Grade 8 alloy steel and left uncoated. The integrated smooth flange measures 1-21\/64 inches (1.3281 inches) in diameter and distributes clamping load evenly across the mating surface. Compliance with IFI 111 and SAE J429 confirms it meets established dimensional and mechanical standards. Licensed tradespeople and industrial maintenance technicians typically specify this fastener where vibration resistance and high tensile strength are required.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is suited for structural assemblies, equipment mounting, and mechanical connections in commercial, industrial, and trade-service environments. The hex drive allows use with standard wrenches and sockets, making it a straightforward fit in HVAC equipment mounting, mechanical room installations, and general fabrication work. The partial threading engages full thread depth in the bearing zone while leaving the shank smooth through thinner mating materials for shear load handling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread size with 2-inch length under head for precise depth control\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof-load strength\u003c\/li\u003e\n  \u003cli\u003eIntegrated smooth flange at 1-21\/64 inches diameter eliminates the need for a separate flat washer\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides a smooth shank section for shear load applications\u003c\/li\u003e\n  \u003cli\u003eHex drive head compatible with standard wrenches and impact sockets\u003c\/li\u003e\n  \u003cli\u003eMeets IFI 111 and SAE J429 standards for dimensional accuracy and mechanical properties\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new-installation fastener for any assembly specifying a 5\/8-11 UNC smooth flange bolt with a 2-inch length under head and Grade 8 alloy steel material to IFI 111 and SAE J429 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician familiar with torque specifications for Grade 8 fasteners at 5\/8-11 UNC. Always consult the equipment manufacturer's torque requirements for the specific joint before final tightening. Ensure mating threads are clean and free of debris before installation. Do not mix with metric fasteners or lower-grade hardware in the same joint 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\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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 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: 1-21\/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: 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: C39047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721915466034,"sku":"C39047","price":40.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/558e4f02bb2e2f25e349a0f60f6628d8.jpg?v=1788583095","url":"https:\/\/voomisupply.com\/products\/value-collection-c39047-flange-bolt-5-8-11-unc-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
