Manufactured from Grade 18-8 stainless steel, this headless fastener provides solid corrosion resistance and reliable holding strength in both indoor and outdoor applications. The cup point geometry bites into the mating surface to resist rotation and axial movement without requiring a protruding head. Driven with a 1\/8-inch hex key, the screw measures 3\/16 inches in overall length. Machinists, maintenance technicians, and industrial assembly professionals select this fastener wherever a low-profile locking solution is required.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in pulleys, collars, hubs, and shaft assemblies where the fastener must sit flush with or below the surface of the component. The 1\/4-20 UNC thread is one of the most common inch-series thread standards in North American industrial and commercial equipment, making this screw a straightforward replacement or standard-stock item. The 18-8 stainless steel construction makes it appropriate for applications with moderate exposure to moisture, mild chemicals, or environments where carbon steel would risk corrosion.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point design bites into mating shaft surface to resist rotation and linear movement\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel provides corrosion resistance for wet or chemically exposed environments\u003c\/li\u003e\n  \u003cli\u003eHeadless profile sits flush with or below the workpiece surface\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread standard for broad compatibility with inch-series tapped components\u003c\/li\u003e\n  \u003cli\u003eDriven with a standard 1\/8-inch hex key\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch overall length suits compact collar and hub applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC cup point set screw suitable for use in collars, shaft hubs, pulleys, and mechanical assemblies that accept a headless inch-series fastener of this thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 1\/8-inch hex key or Allen wrench. Ensure the mating component is properly aligned and that the tapped hole is clean and free of debris before threading. Do not exceed the torque rating appropriate for 18-8 stainless steel at this thread size, as over-tightening can gall the threads. Secure the assembly per applicable mechanical or equipment service standards.\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\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\/16 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: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\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: R63266440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710192550194,"sku":"R63266440","price":1065.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/612fca6dbb95f13ce4bf02e61924d25a.jpg?v=1788464121","url":"https:\/\/voomisupply.com\/products\/value-collection-r63266440-set-screw-1-4-20-x-3-16-in-cup","provider":"Voomi Supply","version":"1.0","type":"link"}
