Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under vibration and torque loads. The cup point geometry bites into mating surfaces to create a positive hold without requiring through-hole access. The 5\/32-inch hex drive accepts a standard hex key for installation in confined spaces. This screw follows ASME\/ANSI B18.3 and ASTM F912 standards, making it a drop-in choice for spec-driven work. Machinists, millwrights, and maintenance technicians use this fastener in shafts, collars, and mechanical assemblies where flush or sub-flush seating is required.\u003c\/p\u003e\n\u003cp\u003eThis set screw fits residential and commercial mechanical assemblies, machine tool fixtures, shaft-to-hub connections, and equipment maintenance applications. The 5\/16-18 UNC thread size and 1-1\/2-inch overall length suit mid-range clamping depth requirements. It is appropriate for any application calling out a cup point set screw to ASME\/ANSI B18.3 or ASTM F912, including OEM replacements and production runs. Minimum order quantity is 100 pieces per order, with individual package quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003eCup point geometry grips mating shaft surfaces to resist rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive accepts standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-inch overall length for deeper engagement in thick hubs and collars\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production fastener for any mechanical assembly requiring a 5\/16-18 UNC cup point set screw to ASME\/ANSI B18.3 or ASTM F912 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a calibrated hex key or L-wrench sized to 5\/32 inch. De-energize and lock out all rotating equipment before installing or adjusting set screws in shaft assemblies. Ensure the tapped hole is clean and free of debris before driving the screw to avoid cross-threading. Follow applicable ASME or facility torque standards for the thread size and grade when consistent preload is required.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/2 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: 5\/32 inches (0.1563 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 Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 101399PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715931734322,"sku":"101399PR","price":5565.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b053bbc13cf80b0095dae219e0edf00.jpg?v=1788519879","url":"https:\/\/voomisupply.com\/products\/value-collection-101399pr-set-screw-5-16-18-x-1-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
