It measures 1\/2 inch in overall length and is driven with a 1\/4-inch hex key. Set screws of this type are used to secure a component — such as a collar, pulley, or gear — onto a shaft by applying direct axial pressure through the flat point against the mating surface. The flat point minimizes marring on hardened shafts and is the preferred point style when the shaft surface must remain undamaged. This fastener meets ASME\/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance for precision mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for industrial, mechanical, and maintenance applications where a UNF 1\/2-20 threaded hole is present. Typical installations include power transmission components, shaft collars, machine tool fixtures, and rotating equipment assemblies. It is installed by licensed millwrights, maintenance mechanics, and industrial technicians working on equipment requiring threaded retention hardware. The Grade 8 alloy steel construction supports use in higher-load applications where standard steel grades are insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF thread for fine-pitch engagement and precise axial positioning\u003c\/li\u003e\n  \u003cli\u003eFlat point design minimizes shaft surface damage during installation\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and proof load requirements\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive for standard Allen key installation\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eFractional inch sizing for compatibility with inch-standard mechanical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series set screw for any mechanical assembly with a 1\/2-20 UNF tapped hole requiring a flat point, hex-drive fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by torquing the set screw with a 1\/4-inch hex key until the flat point seats firmly against the shaft or mating surface. De-energize and lock out all equipment before installing or removing set screws in rotating machinery. Apply a thread-locking compound if vibration is a concern in the application. Verify thread engagement depth meets the requirements of the assembly design to avoid fastener pull-out under load.\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\u003c\/strong\u003e: 0.5 inches (overall length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Flat\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: 0.25 inches (1\/4 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: 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\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: 603402PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691302945074,"sku":"603402PR","price":1116.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1105ad580a4745225400d46c0fcc1d0c.jpg?v=1788282957","url":"https:\/\/voomisupply.com\/products\/value-collection-603402pr-set-screw-1-2-20x1-2-flat-point-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
