Set screws of this type are headless fasteners designed to secure a component — such as a pulley, gear, or collar — against a shaft by bearing directly into the mating surface. The knurled cup point provides a firm bite and improved resistance to loosening under vibration. Drive is accomplished with a 1\/4 inch hex key. This fastener meets ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and mechanical contractors install this type of fastener in industrial and commercial equipment maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for general mechanical assembly and maintenance tasks where a flush or sub-flush fastener is required. The 1\/2-13 UNC thread size and 3\/4 inch overall length fit a wide range of standard shaft-and-hub assemblies. Grade 8 alloy steel construction makes it appropriate for higher-load or higher-torque applications where lower-grade fasteners would be inadequate. This SKU is sold in a minimum order quantity of 10 pieces, with each package containing 1 piece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point digs into mating shaft surface for positive grip and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high-strength, high-torque applications\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex key drive — compatible with standard hex wrenches and Allen keys\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread form for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below surface for clearance-critical installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC knurled cup point set screw for use in shaft collars, shaft couplings, pulleys, gears, and similar mechanical assemblies requiring a Grade 8 alloy steel headless fastener per ASME\/ANSI B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified mechanical technicians. Always de-energize and lock out the equipment before servicing any shaft or rotating assembly. Use a properly sized 1\/4 inch hex key to seat the screw; do not use an undersized key as it may round the socket. Verify thread engagement and confirm the cup point is properly seated against the shaft before returning equipment to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/4 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: 1\/4 inch (0.2500 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\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10 pieces\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: 111571PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716262691122,"sku":"111571PR","price":840.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/778683cfefe5d9ee8cbe2e02b5d571dc.jpg?v=1788523737","url":"https:\/\/voomisupply.com\/products\/value-collection-111571pr-set-screw-1-2-13-x-3-4-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
