Manufactured from Grade 8 alloy steel, it delivers high tensile strength and hardness suited to demanding industrial and trade environments. The 5\/8-18 UNF thread provides fine-pitch engagement, and the 5\/8-inch overall length keeps the fastener compact within the host component. Drive is a 5\/16-inch hex socket, compatible with standard hex keys and Allen drivers. This fastener is built to ASME\/ANSI B18.3 and ASTM F912 standards, making it appropriate for applications where dimensional and mechanical traceability is required.\u003c\/p\u003e\n\u003cp\u003eFlat point set screws like the 603441BR are commonly used to lock collars, hubs, pulleys, and gears onto shafts without damaging the shaft surface. They are found in HVAC blower assemblies, pump drive shafts, and general mechanical equipment across residential and light commercial installations. The fine UNF thread offers precise torque control during installation. This part is typically installed by millwrights, HVAC technicians, and maintenance mechanics working on rotating equipment where shaft retention and minimal surface deformation are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat point tip minimizes shaft surface damage during and after installation\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high hardness and tensile strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF fine-pitch thread for precise engagement and torque control\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive compatible with standard hex keys\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eCompact 5\/8-inch overall length suits tight hub and collar installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-supply set screw for mechanical assemblies requiring a 5\/8-18 UNF flat point fastener in Grade 8 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/16-inch hex key or Allen driver. Always de-energize and lock out rotating equipment before servicing shaft-mounted components. Apply thread-locking compound if specified by the equipment manufacturer to prevent back-out under vibration. Do not exceed the torque range appropriate for Grade 8 alloy steel fasteners of this thread size as specified by the governing equipment documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5\/8 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/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\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\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: 603441BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720870396210,"sku":"603441BR","price":51.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2456b41141299f224be461d9fc295870.jpg?v=1788570260","url":"https:\/\/voomisupply.com\/products\/value-collection-603441br-set-screw-5-8-18-x-5-8-in-flat-point-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
