This partially threaded bolt features a 1\/2-13 UNC thread size with 1-1\/4 inches of thread length and a 2-1\/4 inch length under head. Constructed from alloy steel rated at 170,000 psi tensile strength and conforming to ASTM A574, it delivers the load capacity required in demanding bolted joint applications. The smooth flange bearing surface distributes clamping load evenly without a separate washer. Drive is via a 12-point socket, and the finish is bright and uncoated.\u003c\/p\u003e\n\u003cp\u003eThis flange bolt suits applications in general industrial machinery, equipment assembly, and fabrication work where a high-strength UNC fastener with an integrated smooth flange is specified. The partially threaded shank provides a grip length appropriate for bolted connections requiring a defined unthreaded bearing zone. It is typically installed by machinists, millwrights, maintenance technicians, and industrial assembly professionals working to engineering or OEM torque specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form with 1-1\/4 inches of thread length for reliable engagement\u003c\/li\u003e\n  \u003cli\u003e2-1\/4 inch length under head with partial threading for controlled grip length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated at 170,000 psi tensile strength per ASTM A574\u003c\/li\u003e\n  \u003cli\u003eSmooth flange diameter of 0.735 to 0.750 inches provides integrated load distribution without a separate washer\u003c\/li\u003e\n  \u003cli\u003e12-point drive accepts standard 1\/2 inch socket for high-torque installation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use in dry or controlled environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC smooth flange bolt for use wherever ASTM A574 high-strength alloy steel fasteners are specified in inch-measurement bolted assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or industrial technicians following applicable engineering torque specifications for ASTM A574 alloy steel fasteners. Use a calibrated torque wrench with a 12-point 1\/2 inch socket to achieve the required clamp load. Inspect mating threads and flange seating surface for contamination or damage before assembly. Apply thread lubricant only if specified by the joint design engineer, as lubrication affects torque-to-clamp-load relationships.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\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\u003eLength Under Head\u003c\/strong\u003e: 2-1\/4 inches\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 (nominal 3\/4 inches)\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 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: 170,000 psi tensile strength\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: 711148MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705910264114,"sku":"711148MSC","price":2592.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3010d464bac6b28d995a13dd867c70be.jpg?v=1788431716","url":"https:\/\/voomisupply.com\/products\/value-collection-711148msc-smooth-flange-bolt-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
