It features a 5\/8-11 UNC thread size, a 4-inch length under head, and a hex drive for standard wrench installation. The bolt is partially threaded with a 1.5-inch thread length, leaving the shank unthreaded for shear-resistant joints. Manufactured from Grade 8 alloy steel in an uncoated finish, it meets IFI 111 and SAE J429 standards. The smooth flange distributes clamping load over a 1-21\/64 inch (1.3281 inch) flange diameter, reducing the need for a separate washer. Electricians, pipefitters, millwrights, and general mechanical contractors install this type of fastener in structural and equipment mounting applications.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is suited for industrial, commercial, and heavy-duty mechanical assemblies where a larger bearing surface is needed to prevent bolt pull-through or surface damage. Partial threading makes it appropriate for lap joints and through-bolted connections where the unthreaded shank must carry shear loads. Typical applications include equipment base plates, structural steel connections, machinery mounts, and fabricated assemblies requiring a Grade 8 rated fastener. It is sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load performance\u003c\/li\u003e\n  \u003cli\u003eSmooth flange with 1-21\/64 inch (1.3281 inch) diameter distributes clamping load without a separate washer\u003c\/li\u003e\n  \u003cli\u003ePartial threading with 1.5-inch thread length leaves shank clear for shear-bearing joints\u003c\/li\u003e\n  \u003cli\u003eHex drive head accepts standard open-end, box, and socket wrenches\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; meets 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 inch-series flange bolt for use with 5\/8-11 UNC threaded holes, nuts, and couplings in structural and mechanical assemblies conforming to IFI 111 and SAE J429 specifications.\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 tools sized for the bolt head. Torque the fastener to the value specified in the applicable joint design or equipment service documentation for Grade 8 hardware — do not apply a generic torque value without consulting the engineering specification. Ensure mating threads are clean and free of debris before assembly. When used in structural applications, verify compliance with applicable building or equipment codes 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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Partially Threaded\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: C39053\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700221706546,"sku":"C39053","price":65.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c18fac84891ab1f5c22498673dcd2da.jpg?v=1788387804","url":"https:\/\/voomisupply.com\/products\/value-collection-c39053-flange-bolt-5-8-11-unc-4-inch-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
