Set screws are headless fasteners used to secure a component — such as a gear, pulley, collar, or sprocket — against a shaft by applying direct pressure through the threaded body. The cup point tip bites into the shaft surface to resist rotational and axial movement. The square drive requires a square-key wrench for installation and provides strong torque transfer without stripping. This fastener follows Unified National Coarse (UNC) thread standards and is measured by length under head.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in this size range are common in industrial machinery, HVAC equipment, pump assemblies, and mechanical drive systems. They are used wherever a permanent or semi-permanent shaft-to-hub connection is needed. The 5\/8-11 thread size suits medium-to-heavy-duty applications in both manufacturing and field service environments. Machinists, millwrights, and mechanical service technicians are the primary installers. Minimum order quantity is 10 pieces; this listing represents a package quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip bites into shaft material for secure rotational and axial hold\u003c\/li\u003e\n  \u003cli\u003eSquare drive for high torque input without cam-out\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread — standard fractional inch coarse pitch\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch length measured under head\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction — suitable for general-purpose mechanical applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no plating that could affect dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stocking fastener for any application requiring a 5\/8-11 UNC cup point set screw with a 2-1\/2 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the appropriate square-key wrench sized for the drive recess. De-energize and lock out any equipment before accessing the shaft assembly. Thread engagement should be verified to be full and clean before applying final drive torque. Do not use an impact driver on set screws, as this risks thread damage and over-seating the cup point.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2-1\/2 inches (measured under head)\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: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 409118BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714443280690,"sku":"409118BR","price":24.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/004a03b7825f3df0f4d7fda90c907c1f.jpg?v=1788501549","url":"https:\/\/voomisupply.com\/products\/value-collection-409118br-set-screw-5-8-11-x-2-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
