Sized at 5\/16-18 UNC thread by 3 inches in length, this screw is manufactured from Grade 2 steel with a bright, uncoated finish. The cup point geometry concentrates clamping force at the contact area, providing reliable axial and rotational resistance. Drive type is square, requiring a matching square-key driver. This type of fastener is standard inventory for machinists, millwrights, and maintenance technicians working on rotating equipment, collars, pulleys, and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in this size range are commonly used in light to medium-duty industrial and mechanical maintenance applications. Typical installations include shaft collars, sprocket hubs, gear bores, and similar components where a flush or recessed fastening point is required. The 5\/16-18 UNC thread is a widely used fractional inch coarse thread, compatible with standard tapped holes across a broad range of manufactured components. Grade 2 steel provides adequate strength for general-purpose use in non-critical mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length measured under head, suitable for deeper engagement applications\u003c\/li\u003e\n  \u003cli\u003eCup point geometry concentrates load and resists slippage on shafts and bores\u003c\/li\u003e\n  \u003cli\u003eSquare drive type for positive torque transfer with minimal cam-out\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose mechanical fastening\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no added coating to affect thread fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose set screw for use in any standard 5\/16-18 UNC tapped hole, including shaft collars, hubs, pulleys, and mechanical assemblies requiring a headless cup point fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a square-key driver matched to the screw drive size. Ensure the receiving component is fully threaded to the required depth before installation and that the shaft or seating surface is clean and free of debris. De-energize and lock out any rotating equipment before servicing components secured by set screws. Follow applicable mechanical and industrial safety standards for fastener torque and assembly procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\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 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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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: 0.05 pounds\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: 409067PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696989241650,"sku":"409067PR","price":5153.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/498fb7cbcce95e437a2897202200034a.jpg?v=1788348177","url":"https:\/\/voomisupply.com\/products\/value-collection-409067pr-set-screw-5-16-18-x-3-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
