Measuring 5\/16-18 thread size at 5\/16 inches in overall length, this headless fastener features a knurled cup point that bites into the mating surface to resist rotation and axial movement under load. It is driven with a 5\/32-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Grade 8 alloy steel construction provides high tensile strength suitable for demanding industrial and mechanical fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used in shaft-to-hub connections, collars, pulleys, gears, and similar mechanical assemblies where a headless fastener is required to lock a component in position on a shaft or in a bore. The knurled cup point style provides positive grip on both hardened and soft mating surfaces. Suitable for use in light industrial equipment, HVAC fan assemblies, pump drives, and general mechanical maintenance work performed by service technicians and maintenance trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point digs into mating surface for enhanced torque resistance and axial hold\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and proof-load strength\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive for standard Allen key installation\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC thread form for full engagement along the fastener length\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eFractional inch sizing for compatibility with standard inch-measurement mechanical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for mechanical assemblies requiring a 5\/16-18 UNC headless set screw with a knurled cup point.

De-energize and lock out all rotating or powered equipment before accessing the assembly. Do not exceed the torque capacity of the mating material, particularly when installing into aluminum or soft alloy hubs. Inspect thread condition on both the screw and the receiving bore before installation to ensure full, clean engagement.\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\u003eOverall Length\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Knurled 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\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: 111316PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708929933618,"sku":"111316PR","price":2199.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3cbd9be7efe6dc53aab2b66c02a4ee1.jpg?v=1788449134","url":"https:\/\/voomisupply.com\/products\/value-collection-111316pr-set-screw-5-16-18-x-5-16-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
