Built from 170M PSI alloy steel with a bright uncoated finish, this bolt meets ASTM A574 specifications for socket and structural fasteners. The 12-point drive accepts a 1\/2-inch drive socket, providing high torque capability in confined spaces. The partially threaded shank — threaded 1-1\/4 inches of a 3-inch length under head — allows the unthreaded section to act as a shoulder, improving shear resistance in bolted joints. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt is suited for industrial, mechanical, and structural assembly work where a smooth flange bearing surface is required to distribute clamp load evenly across the mating part. The smooth flange eliminates the need for a flat washer in many applications. Common use cases include equipment mounting, fixture assembly, and machine component fastening in manufacturing and maintenance environments. The 1\/2-13 UNC thread is one of the most widely used coarse-thread sizes in inch-based fastening systems, making this bolt compatible with a broad range of standard nuts and tapped holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction rated to 170M PSI tensile strength per ASTM A574\u003c\/li\u003e\n  \u003cli\u003eSmooth flange with 3\/4-inch diameter distributes clamping load without a separate washer\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank — 1-1\/4 inches of thread on a 3-inch length under head — improves shear resistance\u003c\/li\u003e\n  \u003cli\u003e12-point drive head accepts a 1\/2-inch drive socket for high-torque installation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for indoor and controlled-environment use\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series smooth flange bolt compatible with 1\/2-13 UNC tapped holes and hex nuts conforming to ASTM and ANSI inch-fastener standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 1\/2-inch drive socket or 12-point wrench. De-energize and lock out equipment before fastening or removing bolts from machinery per applicable OSHA lockout\/tagout procedures. The bright uncoated finish provides no corrosion protection — avoid use in wet or corrosive environments without additional protective measures. Apply torque values appropriate for the joint material and grade per applicable engineering specifications or fastener torque tables.\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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: 12 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch\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: 0.735 to 0.750 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: 170M PSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A574\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: 711178MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694552580402,"sku":"711178MSC","price":1265.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02a233f338cfd31e5c314135bdb7be80_5c519bf8-b398-4f7a-97ab-a448a3fadb13.jpg?v=1788325458","url":"https:\/\/voomisupply.com\/products\/value-collection-711178msc-flange-bolt-1-2-13-unc-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
