Sized at 1\/2-13 UNC with a 3-inch length under head, this bolt is partially threaded with 1.25 inches of thread engagement. The flange diameter measures 1.0781 inches (1-5\/64 inches), distributing clamp load over a wider surface area without requiring a separate washer. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, it meets SAE J429 standards for mechanical and chemical properties. Hex drive allows installation with standard wrenches or sockets. This fastener is suited for structural and mechanical assembly work in industrial, agricultural, and equipment manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in applications where a smooth, non-serrated flange is needed to avoid marking or rotating against finished or coated surfaces. Typical installations include heavy equipment frames, agricultural machinery, hydraulic component mounting, and structural steel assemblies. The Grade 8 alloy steel construction makes it appropriate for high-stress joints requiring elevated tensile and proof load strength. The phosphate and oil finish provides moderate corrosion resistance and helps with initial installation torque control. Sold individually with a minimum order quantity of 50 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread size with 1.25 inches of partial threading\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head for deeper grip in thick assemblies\u003c\/li\u003e\n  \u003cli\u003eSmooth flange diameter of 1.0781 inches acts as an integrated bearing surface\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction meets SAE J429 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish for moderate corrosion resistance and reduced galling\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard 3\/4-inch wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an inch-series UNC fastener suitable for use in any application requiring a 1\/2-13 partially threaded smooth flange bolt with Grade 8 alloy steel strength and SAE J429 compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical assembly technicians, millwrights, or maintenance personnel using standard hand or power tools with a 3\/4-inch hex drive. Always de-energize or lock out equipment before servicing fastened assemblies. Apply consistent torque using a calibrated torque wrench and follow the assembly engineer's specified torque values for the joint design. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.25 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: 1.0781 inches (1-5\/64 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: Phosphate and Oil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: 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: 0.22 pounds\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: 50\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: 821776MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51704808341810,"sku":"821776MSC","price":14873.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/022a77dae21a4373d3e1524204cad719.jpg?v=1788425135","url":"https:\/\/voomisupply.com\/products\/value-collection-821776msc-flange-bolt-1-2-13-unc-3in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
