Sized at 1\/2-13 UNC with a 2-inch length under head, this bolt features partial threading with 1-1\/4 inches of thread engagement. The integrated smooth flange measures 1-5\/64 inches (1.0781 inches decimal) in diameter and distributes clamp load across a wider surface area without the need for a separate washer. Manufactured from Grade 8 alloy steel and left uncoated, it meets IFI 111 and SAE J429 standards. Licensed tradespeople and maintenance professionals in mechanical, structural, and industrial applications install this fastener where controlled load distribution and tensile strength are priorities.\u003c\/p\u003e\u003cp\u003eThis flange bolt is suited for use in heavy-duty mechanical assemblies, structural connections, and industrial equipment where Grade 8 tensile strength is specified. The partially threaded shank allows for a firm grip in the unthreaded section, making it appropriate for applications requiring precise shear load handling. It is driven with a standard hex wrench or socket and installs in any orientation where a flanged fastener is called for. Minimum order quantity is 10 pieces per purchase.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size with 1-1\/4 inches of thread length for reliable engagement\u003c\/li\u003e\n\u003cli\u003e2-inch length under head — measured from bearing face to tip\u003c\/li\u003e\n\u003cli\u003eSmooth flange diameter of 1-5\/64 inches (1.0781 inches) distributes clamping load without a separate washer\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved shear resistance in the unthreaded grip zone\u003c\/li\u003e\n\u003cli\u003eUncoated finish — compatible with field-applied coatings or used bare in dry or protected environments\u003c\/li\u003e\n\u003cli\u003eConforms to IFI 111 and SAE J429 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-13 UNC smooth flange bolt for use in any application requiring a Grade 8 alloy steel flanged fastener conforming to IFI 111 and SAE J429 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson familiar with torque requirements for Grade 8 fasteners. Always consult the equipment manufacturer's torque specifications before installation. Ensure mating threads are clean and free of debris before driving the bolt. Do not use impact tools at full power without a torque-limiting setting, as over-torquing Grade 8 fasteners can induce thread damage or bolt failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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 Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\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: 1-5\/64 inches (1.0781 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: 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C39037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691526816050,"sku":"C39037","price":28.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a92d11a9ccb8bba7f9af7926628a16bd.jpg?v=1788286524","url":"https:\/\/voomisupply.com\/products\/value-collection-c39037-flange-bolt-1-2-13-unc-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
