It features a 1\/4-20 UNC thread with a 1\/2-inch length under the head and is fully threaded along its entire length. The hex drive provides reliable torque transfer with standard tooling. Constructed from Grade 8 alloy steel with a phosphate and oil finish, this bolt offers high tensile strength and corrosion resistance suitable for demanding mechanical and structural assemblies. A 9\/16-inch smooth flange distributes clamping load evenly, eliminating the need for a separate washer in most installations.\u003c\/p\u003e\n\u003cp\u003eThis bolt is well suited for automotive, industrial, and equipment assembly applications where a smooth flange face is required to protect mating surfaces or provide load distribution without a washer. It is commonly used by maintenance technicians, millwrights, and assembly professionals working on machinery, brackets, and structural components. The 1\/4-20 UNC thread is one of the most widely used inch-series thread sizes, making this bolt a standard stocking item in maintenance, repair, and operations environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC fully threaded shank for maximum thread engagement across the full 1\/2-inch length under head\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eSmooth 9\/16-inch flange diameter distributes clamping load and eliminates separate washer requirement\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish provides corrosion and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eHex drive compatible with standard open-end, box, and socket wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J429 standards for mechanical and material requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance stock fastener for any assembly requiring a 1\/4-20 UNC smooth flange bolt with a 1\/2-inch length under head and Grade 8 strength rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified maintenance technicians or assembly professionals using standard hex wrenches or sockets. Ensure mating threads are clean and free of debris before installation. Apply torque values in accordance with the equipment manufacturer specifications or applicable standards for Grade 8 fasteners. Do not exceed recommended torque for the 1\/4-20 thread size, as over-tightening can cause thread stripping or flange distortion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Fully 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: 0.5625 inches (9\/16 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\u003eWeight\u003c\/strong\u003e: 0.0138 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 821192MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699253903666,"sku":"821192MSC","price":2591.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0702bb342ff8fdae1f162eb856abef67.jpg?v=1788374196","url":"https:\/\/voomisupply.com\/products\/value-collection-821192msc-flange-bolt-1-4-20-unc-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
