Set screws are fully threaded fasteners with no head, designed to secure a component — such as a collar, pulley, or gear — against a shaft by applying axial force at the point of contact. The cup point geometry bites into the mating surface to resist rotation and axial movement. Drive engagement is through a 1\/8 inch internal hex socket, requiring a standard hex key for installation. This fastener meets ASME\/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance for industrial and mechanical assembly applications.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in 1\/4-20 UNC thread are commonly used in light to medium-duty mechanical assemblies including motor shafts, conveyor components, valve stems, and machinery fixtures. The 3\/4 inch overall length provides sufficient engagement depth for most standard hub thicknesses. Grade 8 alloy steel construction suits applications where higher clamp load and resistance to vibration loosening are required. Installers in maintenance, manufacturing, and mechanical service trades use this fastener when securing rotating or sliding components to shafts without a traditional bolt head profile.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread with 3\/4 inch overall length for consistent shaft engagement\u003c\/li\u003e\n\u003cli\u003eCup point geometry provides positive bite into mating shaft surface to resist rotation\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for higher tensile and proof load ratings\u003c\/li\u003e\n\u003cli\u003e1\/8 inch internal hex drive for use with standard hex keys or L-wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n\u003cli\u003eFully threaded headless design allows flush or below-surface installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for any application requiring a 1\/4-20 UNC cup point set screw with 3\/4 inch overall length and 1\/8 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 1\/8 inch hex key or T-handle driver; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. Degrease the threaded bore and shaft contact area before installation to ensure accurate seating and consistent clamping force. Where set screws secure rotating shaft components, verify shaft hardness is sufficient to allow the cup point to seat properly. Follow applicable machinery safety lockout\/tagout procedures before installing or removing set screws from powered equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/4 inches (overall)\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: Internal Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/8 inches (0.1250 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\u003eThread Standard\u003c\/strong\u003e: UNC \/ UNF\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: 0.01 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: 101321P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699790414130,"sku":"101321P","price":4103.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94509742c96770daae8f394cbb277a8e.jpg?v=1788381001","url":"https:\/\/voomisupply.com\/products\/value-collection-101321p-set-screw-1-4-20-x-3-4-in-cup-point-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
