Manufactured from Grade 18-8 stainless steel, it offers solid corrosion resistance in both indoor and outdoor environments. The screw measures 3\/8-16 thread size by 1-1\/4 inches in overall length and is driven with a 3\/16-inch hex key. The cup point bites into the mating surface to resist rotational and axial movement. This type of fastener is commonly installed by machinists, maintenance mechanics, and industrial trades in shaft-to-hub connections, collars, and mechanical positioning applications.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in general-purpose mechanical and industrial applications where a headless, flush-mount fastener is required. Typical scenarios include securing pulleys, gears, and collars to shafts. The UNC thread form is the standard inch-series coarse thread, making it compatible with common tapped holes in that size. Grade 18-8 stainless steel makes it a practical choice where mild chemical exposure or moisture is a factor. This item is sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface for positive holding force\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inches overall length for adequate thread engagement depth\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex drive accepts standard hex keys and T-handles\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below the surface for clearance-sensitive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC cup point set screw suitable for any tapped hole or collar machined to that thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the screw into a pre-tapped hole using a 3\/16-inch hex key. Ensure the mating shaft or surface is clean and free of debris before seating the cup point. Apply thread-locking compound where vibration may back the fastener out over time. Do not exceed the torque capacity of the 18-8 stainless material, and avoid using impact tools that may gall stainless threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 1-1\/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: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 3\/16 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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: R63263442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691870224690,"sku":"R63263442","price":1039.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0ce180c959c96a497bedeaeb6f5fb4c.jpg?v=1788290620","url":"https:\/\/voomisupply.com\/products\/value-collection-r63263442-set-screw-3-8-16-x-1-1-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
