It features a 3\/8-16 UNC thread with a 2-inch length under head and partial threading of 1 inch, leaving a smooth shank section for shear-load bearing. The 13\/16-inch flange diameter distributes clamping load across a wider bearing surface without the need for a separate washer. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, this bolt meets SAE J429 standards and delivers the tensile and proof-load ratings that demanding fastening applications require. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is suited for automotive, heavy equipment, agricultural machinery, and general industrial assembly work where a secure, washer-free clamping surface is needed. The partially threaded shank makes it appropriate for joints where the bolt passes through a clearance hole and threads into a tapped bore or nut, providing better shear resistance than a fully threaded fastener. The phosphate and oil finish offers moderate corrosion resistance and aids in controlled torque application during installation. Minimum order quantity is 100 pieces, making this part appropriate for production-line procurement or high-volume maintenance operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank (1 inch of thread) improves shear load performance at joint interfaces\u003c\/li\u003e\n  \u003cli\u003e13\/16-inch smooth flange integrates a load-spreading surface directly on the bolt head, eliminating a separate washer\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction meets SAE J429 proof load and tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish provides moderate corrosion protection and aids torque control during assembly\u003c\/li\u003e\n  \u003cli\u003eHex drive head for use with standard open-end, box, or socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series smooth flange bolt for use in any application calling for a 3\/8-16 UNC, 2-inch Grade 8 partially threaded flange fastener per SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a standard hex wrench or socket sized for the bolt head. Follow the torque specifications provided by the equipment or assembly manufacturer for Grade 8 fasteners at this thread size, and ensure mating threads are clean and free of debris before installation. Do not reuse bolts that have been torqued to yield. Consult applicable industry standards for proper joint design and fastener selection when used in structural or safety-critical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 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 inch (partially threaded)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 13\/16 inches (0.8125 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: 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: 0.0688 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: 821140MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693849149746,"sku":"821140MSC","price":13632.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46ad26794f392093d73442904807b115.jpg?v=1788318159","url":"https:\/\/voomisupply.com\/products\/value-collection-821140msc-flange-bolt-3-8-16-unc-2in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
