It features a 5\/8-18 UNF thread form on a fully threaded shank measuring 1.5 inches under the head. The integrated smooth flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer in many installations. Manufactured from Grade 8 alloy steel, the bolt delivers high tensile strength suitable for heavy-duty joint assemblies. Drive engagement is through a standard hex head. The uncoated finish is typical for applications where a coating will be applied on-site or where bare alloy steel is otherwise appropriate.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in industrial, automotive, agricultural, and heavy equipment assemblies where a UNF fine-thread fastener with an integral flange is required. The smooth flange face is appropriate where a serrated locking flange is not needed or where mating surfaces require a clean bearing seat. Installers in HVAC equipment mounting, pump and motor assembly, and structural bracketing commonly specify this bolt type when working with tapped holes or standard hex nuts in fine-thread configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fully threaded shank — 1.5 inches length under head for shallow to moderate joint stacks\u003c\/li\u003e\n  \u003cli\u003eSmooth flange diameter of 1-21\/64 inches (1.3281 inches) provides broad load distribution without a separate washer\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction meets high tensile and proof load requirements\u003c\/li\u003e\n  \u003cli\u003eHex drive head for use with standard wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — compatible with field-applied coatings or bare-steel assemblies\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 UNF flange bolt for use with 5\/8-18 tapped holes or matching hex nuts in inch-measurement assemblies conforming to IFI 111 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench or socket sized for a 5\/8-inch hex head fastener. Torque to the joint specification required by the equipment manufacturer or applicable structural standard — do not rely on generic torque tables without confirming the joint design. Inspect mating threads and flange seating surface for debris or damage before fastening. Grade 8 fasteners should not be reused after experiencing yield-level loading or visible deformation.\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\u003eThread Style\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5 inches\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 Coating\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\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\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: C39064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722822648114,"sku":"C39064","price":35.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8375e93e2c95ede98a21083e26d7a81.jpg?v=1788596436","url":"https:\/\/voomisupply.com\/products\/value-collection-c39064-flange-bolt-5-8-18-unf-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
