Set screws are headless fasteners used to secure a component — such as a collar, gear, or pulley — against a shaft by applying direct pressure through the point. The cup point geometry bites into the mating surface for positive holding force. The 1\/4-inch hex drive accepts a standard hex key for installation and removal. This fastener meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, ASTM A574, and MS16555 standards, making it suitable for demanding mechanical assemblies where precise torque and retention are required.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in the 1\/2-13 UNC thread size are widely used in industrial, commercial, and mechanical maintenance applications. Typical install scenarios include securing shaft collars on rotating equipment, fixing hubs to drive shafts, and locking adjustment mechanisms in machinery. Maintenance technicians, millwrights, and mechanical contractors commonly specify Grade 8 alloy steel set screws in these applications where elevated strength and resistance to loosening under vibration are priorities. This part is sold in a package quantity of 50.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch length measured under head (headless body length)\u003c\/li\u003e\n  \u003cli\u003eCup point geometry provides positive grip and penetration into mating shaft surfaces\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive accepts standard hex keys and T-handles\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, ASTM A574, and MS16555 fastener standards\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 for use in any tapped hole conforming to that thread specification; suitable as a direct replacement or stock fastener in mechanical assemblies requiring a Grade 8 alloy steel headless screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 1\/4-inch hex key; ensure the key is fully seated before applying torque to prevent rounding the drive socket. De-energize and lock out all rotating equipment before servicing any shaft or collar secured by this fastener, in accordance with applicable LOTO procedures. Inspect the mating shaft surface for damage or debris before seating the cup point. Do not exceed the torque rating specified in the applicable fastener standard for this thread size and grade.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/4 inches (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: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/4 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standards\u003c\/strong\u003e: ANSI B18.3, ANSI B18.8.2, ANSI B2.2, ASTM A574, MS16555\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\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: C771468\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693588676914,"sku":"C771468","price":71.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_1a41ff81-87ad-461b-92a9-84c6ec66c654.jpg?v=1788314551","url":"https:\/\/voomisupply.com\/products\/value-collection-c771468-set-screw-1-2-13-x-3-4-in-cup-point-gr8","provider":"Voomi Supply","version":"1.0","type":"link"}
