Set screws are fully threaded fasteners with no head, designed to secure a component — such as a collar, gear, or pulley — against or onto a shaft by bearing the cup point directly into the shaft surface. The square drive socket accepts a square-key wrench for high-torque installation in confined spaces. This screw follows UNC thread standards and uses a length-under-head measurement convention. It is a general industrial fastener installed by machinists, millwrights, and maintenance technicians across a wide range of mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in this size range are common in industrial machinery, power transmission components, shaft collars, and mechanical assemblies where a positive, bite-in hold is required. The 9\/16-12 UNC thread and 3 inch length suit medium-to-heavy shaft diameters where deeper thread engagement and extended point contact are needed. This fastener ships in a minimum order quantity of 5 pieces, making it suitable for maintenance stock or small assembly runs in manufacturing, industrial service, and mechanical contracting environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip bites into shaft surface for positive rotational and axial hold\u003c\/li\u003e\n  \u003cli\u003eSquare drive socket allows high-torque installation with a square-key wrench\u003c\/li\u003e\n  \u003cli\u003e9\/16-12 UNC thread standard for broad tool and tap compatibility\u003c\/li\u003e\n  \u003cli\u003e3 inch length provides extended thread engagement for deeper shaft applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 alloy steel construction for strength in general industrial use\u003c\/li\u003e\n  \u003cli\u003eFully threaded, headless design fits flush or below surface in tapped holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC-thread cup point set screw for use in any tapped hole accepting a 9\/16-12 thread, including shaft collars, shaft couplings, pulleys, gears, and other power transmission components requiring a headless fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a square-key wrench sized for the drive socket. Always de-energize and lock out the associated machinery before installing or removing set screws from rotating components, following applicable LOTO procedures. Do not overtighten beyond the point of firm shaft contact, as cup point penetration depth affects shaft integrity. Inspect threads and mating tapped holes for damage before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 inches (length 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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\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: 0.01 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: 409214PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721089810738,"sku":"409214PR","price":3080.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdc5a50ab16be4c6936724c1e4ea9847.jpg?v=1788573363","url":"https:\/\/voomisupply.com\/products\/value-collection-409214pr-set-screw-9-16-12-x-3-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
