Measuring 1\/4 inch in overall length, it is driven by a 1\/8-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. This type of fastener is installed by machinists, millwrights, and maintenance technicians to lock shafts, collars, pulleys, and similar components in position without a protruding head. The knurled cup point bites into the mating surface for improved retention under vibration and torque loads.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for general industrial and mechanical assembly applications where a flush or recessed fastener is required. Typical uses include securing shaft collars, gear hubs, and handwheels in light to heavy machinery. The fine 1\/4-28 UNF thread pitch provides precise depth adjustment and greater thread engagement per inch compared to coarse thread alternatives, making it appropriate for applications with thin wall sections or vibration-prone assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point for enhanced grip and bite into mating shaft or surface\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for precise positioning and strong thread engagement\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex drive compatible with standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows fully recessed installation in shaft or hub\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard service fastener for mechanical assemblies requiring a 1\/4-28 UNF knurled cup point set screw with a 1\/8-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist, millwright, or qualified maintenance technician using a calibrated hex key of the correct 1\/8-inch size. Always de-energize and lock out the equipment before tightening or removing set screws on rotating components. Thread the screw in by hand first to confirm proper engagement and avoid cross-threading. Do not reuse a set screw that shows deformation at the cup point, as reliable clamping force cannot be guaranteed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1\/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\/8 inches (0.1250 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: UNF\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: 111265PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708117516594,"sku":"111265PR","price":2047.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b193b9e6b1be1ab508a7723e54e19ef.jpg?v=1788444346","url":"https:\/\/voomisupply.com\/products\/value-collection-111265pr-set-screw-1-4-28-x-1-4-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
