Threaded to the 1\/4-20 UNC standard with a full 1-1\/2 inch length under the head, this bolt distributes clamping load across a 9\/16 inch smooth flange, eliminating the need for a separate washer in many installations. The Grade 8 alloy steel construction meets SAE J429 specifications, making it suitable for high-stress joints. A phosphate and oil finish provides baseline corrosion resistance and lubricity during installation. Licensed trades and industrial maintenance technicians working on equipment assemblies, brackets, and structural connections are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in residential and light commercial mechanical systems, equipment mounting, and general structural fastening where a 1\/4-20 UNC thread pattern is specified. The smooth flange bearing surface is appropriate for applications requiring even load distribution without a separate washer. Typical uses include HVAC equipment brackets, electrical panel supports, plumbing fixture mounting hardware, and general industrial assembly where Grade 8 strength is required by design specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread, fully threaded at 1-1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction meets SAE J429 standard\u003c\/li\u003e\n  \u003cli\u003eSmooth 9\/16 inch flange diameter distributes load without a separate washer\u003c\/li\u003e\n  \u003cli\u003ePhosphate and oil finish provides corrosion resistance and aids installation torque\u003c\/li\u003e\n  \u003cli\u003eHex drive for standard socket or wrench installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose 1\/4-20 UNC smooth flange bolt for use in any application requiring SAE J429 Grade 8 fastener performance with a flanged bearing surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed tradespeople or qualified maintenance technicians using standard hex sockets or open-end wrenches. Always de-energize and isolate equipment before fastening or removing hardware in electrical or mechanical assemblies. Apply torque values per the engineering specification for the joint being assembled, as Grade 8 fasteners support higher clamping loads than lower-grade hardware. Inspect thread engagement and flange seating before final tightening.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 inches\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: 9\/16 inches (0.5625 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: 0.0238 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: 822689MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693363790130,"sku":"822689MSC","price":3872.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44a65bdea9be527563d4748deaa216f9.jpg?v=1788311260","url":"https:\/\/voomisupply.com\/products\/value-collection-822689msc-flange-bolt-1-4-20-unc-1-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
