Built from Grade 8 alloy steel with a phosphate and oil finish, this bolt delivers reliable corrosion resistance and clamping force in demanding mechanical and industrial assemblies. The 1\/2-13 UNC thread pattern and 2-1\/2 inch length under head make it a standard choice for structural and equipment fastening where precise thread engagement matters. Partial threading leaves a smooth shank section that improves shear resistance in fitted or close-tolerance installations. Licensed tradespeople and assembly technicians working to SAE J429 standards will find this bolt meets specification for critical joint applications.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for general mechanical assembly, industrial equipment, and structural fastening where a smooth, integrated flange distributes clamp load across the joint face. The 1-5\/64 inch (1.0781 inch) flange diameter provides a broad seating surface, reducing the chance of surface damage or pull-through on softer base materials. It is appropriate for use in maintenance, repair, and original equipment manufacturing contexts across a range of industrial and commercial settings where Grade 8 strength is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load requirements per SAE J429\u003c\/li\u003e\n  \u003cli\u003eSmooth flange with 1-5\/64 inch (1.0781 inch) diameter provides integrated washer-like bearing surface\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank — 1-1\/4 inch thread length on a 2-1\/2 inch body — improves shear strength in fitted joints\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for fast engagement and strong pull-out resistance\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish for moderate corrosion protection and consistent installation torque\u003c\/li\u003e\n  \u003cli\u003eHex drive for standard wrench and socket installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and replacement fastener for assemblies specifying 1\/2-13 UNC partially threaded smooth flange bolts to SAE J429 Grade 8 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanical assemblers or maintenance technicians. De-energize and lockout-tagout all equipment before fastener service per applicable safety procedures. Use a calibrated torque wrench and apply Grade 8 torque values appropriate to the joint specification — do not exceed the rated torque for this thread size and grade as listed in the applicable engineering or maintenance documentation. Inspect mating threads for damage or contamination before assembly.\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\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/4 inches (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\u003eThread Standard\u003c\/strong\u003e: UNC\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\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: 0.1911 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: 821767MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714652078386,"sku":"821767MSC","price":14334.28,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c8beb27ade7bf13f44bb844c86029b4.jpg?v=1788504480","url":"https:\/\/voomisupply.com\/products\/value-collection-821767msc-flange-bolt-1-2-13-unc-2-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
