This fully threaded fastener uses a 3\/8-16 UNC thread and measures 4-1\/2 inches in length under head. It is manufactured from alloy steel to Grade 2 specifications, providing solid tensile strength for general industrial and trade use. The cup point tip bites into the mating surface to resist rotation and axial movement without requiring a protruding head. It is installed using a square drive. Maintenance technicians, millwrights, and mechanical contractors are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for securing collars, hubs, pulleys, gears, and similar components onto shafts in both residential and light commercial mechanical assemblies. The 3\/8-16 UNC thread size is a common standard pitch found in a wide range of machined components and hardware. The 4-1\/2 inch length accommodates deeper engagement requirements where shorter set screws are insufficient. Applications span HVAC equipment, pump assemblies, conveyor systems, and general industrial machinery maintenance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip grips mating shaft surface to resist axial and rotational movement\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread for broad compatibility with standard inch-fractional hardware\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length provides deep thread engagement for demanding applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction at Grade 2 for reliable tensile performance\u003c\/li\u003e\n  \u003cli\u003eSquare drive socket for positive wrench engagement during installation\u003c\/li\u003e\n  \u003cli\u003eLength measured under head per standard fractional inch convention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-fractional set screw for use in any threaded bore or collar accepting a 3\/8-16 UNC thread pattern.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the screw into a pre-tapped 3\/8-16 UNC bore using a square drive key or wrench. Power down or de-energize all associated equipment before beginning work. Apply appropriate thread-locking compound if the application involves vibration. Do not over-torque, as alloy steel set screws can seize or deform softer shaft materials.\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: 4-1\/2 inches (measured 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: Square\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 2\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: 409082PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714388656434,"sku":"409082PR","price":2037.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c8f619d4d5eeb35c127398fc41a9b42.jpg?v=1788500753","url":"https:\/\/voomisupply.com\/products\/value-collection-409082pr-set-screw-3-8-16-x-4-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
