Manufactured from Grade 8 alloy steel, this fastener delivers high tensile and torsional strength suited to demanding industrial and maintenance environments. The 5\/8-11 UNC thread and 2.5-inch overall length make it appropriate for medium-to-heavy locking tasks. Drive engagement is through a 5\/16-inch hex key socket. Each package contains 10 screws. Licensed tradespeople, maintenance mechanics, and millwrights install this type of fastener in production machinery, conveyor systems, and drive shaft assemblies.\u003c\/p\u003e\u003cp\u003eCup point set screws seat directly against a shaft or workpiece surface, creating a localized bite that resists rotational and axial movement. This fastener is suited for use in collars, pulleys, gears, and similar mechanical components where a headless fastener is required to sit flush with or below the surface of the host part. The 5\/8-11 UNC thread size is common in heavier-duty industrial equipment. This product ships in a 10-piece package, making it practical for service stock and job-lot quantities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point geometry provides positive shaft engagement and resistance to loosening under vibration\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional load capacity\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC thread for compatibility with standard inch-series tapped bores\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex key drive for installation with standard L-keys or T-handle wrenches\u003c\/li\u003e\n\u003cli\u003eHeadless design allows the fastener to sit flush or below the surface of the mating part\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service stock fastener for any mechanical assembly requiring a 5\/8-11 UNC threaded cup point set screw with a 2.5-inch overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed mechanics or millwrights using a 5\/16-inch hex key. Power down and de-energize all equipment before servicing shaft or hub assemblies. Apply thread-locking compound where vibration is a concern, per the equipment manufacturer's service guidelines. Do not exceed the rated torque specified by the assembly manufacturer for the host component.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\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: 5\/16 inches (0.3125 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\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 40433\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720945631538,"sku":"40433","price":40.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/973ed93553021cd54635323062b3bae0.jpg?v=1788571317","url":"https:\/\/voomisupply.com\/products\/value-collection-40433-cup-point-set-screw-5-8-11-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
