Manufactured from alloy steel to ASTM F912 material grade, this fastener meets ASME\/ANSI B18.3 dimensional standards. The cup point geometry bites into the mating surface to resist rotational and axial movement without the need for a through-hole. It is driven with a 1\/4-inch hex key. Trades and maintenance professionals use this screw wherever a flush or recessed fastener is required, such as securing collars, pulleys, gears, and shaft-mounted components across industrial and mechanical maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in rotating shaft assemblies, collar and hub retention, and general mechanical fastening where a protruding fastener head is not acceptable. The 1\/2-20 UNF thread provides fine-pitch engagement for controlled clamping force. It is appropriate for both original equipment assembly and field repair work in industrial, HVAC, and mechanical service environments. Installation requires a standard 1\/4-inch hex key driver. Sold individually per package; a minimum order quantity of 5 pieces applies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry grips mating shaft surface to prevent slippage under load\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF fine-thread for precise torque control and strong thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated to ASTM F912 material grade for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 dimensional standard for hex socket set screws\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive accepts standard hex key or T-handle driver\u003c\/li\u003e\n  \u003cli\u003eFully headless 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 ASME\/ANSI B18.3 hex socket cup point set screw; compatible with any 1\/2-20 UNF threaded collar, hub, or mechanical component requiring a cup point fastener of 1-1\/2-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or mechanical maintenance technicians using a calibrated 1\/4-inch hex key or torque-limiting driver. De-energize and lock out all rotating equipment before installing or adjusting set screws. Ensure the mating shaft and threaded bore are clean and free of debris prior to installation. Do not substitute a larger or smaller hex key, as this can round the socket drive or result in under-torquing 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: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength (Overall)\u003c\/strong\u003e: 1-1\/2 inches\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: 1\/4 inch (0.2500 inch)\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: ASTM F912\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3\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: 0.05 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: 601354PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698300551474,"sku":"601354PR","price":750.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72dc3e5311b932a00dbf24cdc2ba80e1.jpg?v=1788360798","url":"https:\/\/voomisupply.com\/products\/value-collection-601354pr-set-screw-1-2-20-x-1-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
