Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength suitable for demanding industrial and trade applications. The cup point bites into the mating surface to resist axial and rotational movement without requiring a through-hole. Drive is a 5\/32-inch hex socket, compatible with standard hex keys and Allen wrenches. This fastener measures 5\/16-18 thread size by 5\/16-inch overall length and meets ASME\/ANSI B18.3 and ASTM F912 standards. It is installed by maintenance technicians, millwrights, and mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in shaft-to-hub connections, collars, pulleys, sprockets, and similar mechanical assemblies where a headless fastener is required. The 5\/16-18 UNC thread pattern fits standard tapped holes in that specification. Applications span light industrial equipment, HVAC blower assemblies, pump shafts, and general mechanical assemblies where a positive hold on a shaft or flat is needed. The cup point design is appropriate where minor surface marking of the mating part is acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into mating surface to resist rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive works with common hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below surface to avoid snagging or interference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation set screw for any assembly with a 5\/16-18 UNC tapped hole requiring a cup point, headless fastener per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSet screws are typically installed by millwrights, maintenance technicians, or mechanical contractors using a calibrated hex key or Allen driver. De-energize and lock out all rotating equipment before installing or removing set screws. Apply thread-locking compound if vibration is a concern and torque to the fastener specification listed in the applicable engineering standard. Do not substitute a worn or undersized hex key, as rounding the socket will damage the fastener.\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: 5\/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 Socket\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\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: 101381PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694350663986,"sku":"101381PR","price":1795.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e919ee1af6152ece892f3484231c7e04.jpg?v=1788323471","url":"https:\/\/voomisupply.com\/products\/value-collection-101381pr-set-screw-5-16-18-x-5-16-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
