Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under vibration and dynamic load. The 1\/2-13 UNC thread and 1-1\/2 inch overall length make it well suited for medium-to-heavy duty clamping applications. Drive is a 1\/4 inch hex (Allen) socket. Compliance with ASME\/ANSI B18.3 and ASTM F912 standards confirms dimensional accuracy and mechanical performance. Machinists, millwrights, and maintenance technicians rely on this style of fastener to lock shafts, collars, pulleys, and gears in position without a protruding head.\u003c\/p\u003e\n\u003cp\u003eCup point set screws are a standard component in rotating machinery, conveyor systems, pump assemblies, and HVAC equipment where shaft-to-hub retention is required. The cup point geometry bites into the shaft surface to resist axial and rotational movement. This fastener is appropriate for steel and cast iron shaft materials in both new installations and maintenance replacement work. Minimum order quantity is 50 pieces per order; package quantity is 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface for positive retention\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard tapped bores\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex drive accepts standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eNo protruding head — fully recessed when installed flush or below surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC cup point set screw suitable for use in any threaded bore conforming to ASME\/ANSI B18.3 specifications, including shaft collars, hubs, pulleys, couplings, and mechanical assemblies requiring headless fastening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/4 inch hex key or Allen bit driver. Ensure the mating threaded bore is clean and free of debris before threading. Torque to the fastener manufacturer's published specification for Grade 8 alloy steel at this thread size — do not use generic torque values. Always de-energize and lock out any rotating equipment before servicing or installing set screws in shaft assemblies.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 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: 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\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\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\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: 40419\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695782691122,"sku":"40419","price":31.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f79817697be46d7e99424867531cb48.jpg?v=1788338198","url":"https:\/\/voomisupply.com\/products\/value-collection-40419-cup-point-set-screw-1-2-13-x-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
