This fully threaded headless fastener uses a 1\/4-inch hex drive and features a cup point tip that bites into the mating surface to resist rotation and axial movement. The 1\/2-13 UNC thread and 4-1\/2-inch overall length make it suitable for applications requiring deep thread engagement and strong clamping force. Manufactured from alloy steel, it meets ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, maintenance mechanics, and industrial technicians install this type of fastener in shafts, collars, pulleys, and similar components.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in mechanical power transmission assemblies where a flush or recessed fastener is required. Typical applications include securing shaft collars, sprockets, gears, and hubs against a rotating shaft. The cup point configuration provides a reliable bite on both hardened and unhardened shaft surfaces. It is well suited for general industrial maintenance, OEM machine assembly, and field repair work where a standard UNC alloy steel set screw is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip grips shaft surfaces to prevent rotation and axial slip\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread with 4-1\/2-inch overall length for deep engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive accepts standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below the mating surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard service fastener for mechanical assemblies requiring a 1\/2-13 UNC cup point set screw with a 4-1\/2-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance mechanics using a 1\/4-inch hex key or L-wrench. De-energize and lock out any rotating machinery before installing or removing set screws. Clean the threaded bore and shaft contact point before installation to ensure full thread engagement. Do not use impact drivers or oversized hex tools, as these can damage the hex socket or strip the threads.\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\u003c\/strong\u003e: 4-1\/2 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 601337PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716566450482,"sku":"601337PR","price":2058.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/648cba14da46c4ae702c0b149476d4aa.jpg?v=1788528020","url":"https:\/\/voomisupply.com\/products\/value-collection-601337pr-set-screw-1-2-13-x-4-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
