Set screws are headless fasteners that thread fully into a tapped hole to secure a component against a shaft or mating surface. The cone point tip bites into the mating surface for a strong, vibration-resistant hold. This fastener uses a 3\/16 inch hex key drive and measures 1\/2 inch in overall length. It meets ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians install these in mechanical assemblies where a flush or recessed fastener is required.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for general industrial and mechanical applications including shaft collars, shaft couplings, pulleys, gears, and similar rotating components. The cone point geometry is preferred when a permanent or semi-permanent installation is acceptable, as the tip cold-works into the shaft surface for maximum axial and torsional holding strength. The UNC thread standard makes it compatible with standard inch-series tapped holes common in North American industrial equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCone point tip provides high holding force by embedding into the mating shaft surface\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003e3\/16 inch hex key drive for precise torque application in tight clearances\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush or below the workpiece surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-16 UNC tapped holes in shaft collars, couplings, pulleys, gears, and similar mechanical assemblies requiring a cone point set screw.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 3\/16 inch hex key or Allen driver. De-energize and lock out all equipment before installing or adjusting set screws on rotating shafts. Ensure the tapped hole is clean and free of debris before threading the fastener in. Do not exceed the torque rating of the fastener or the tapped hole material, and verify thread engagement depth meets applicable design requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/2 inch (overall)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone\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: 3\/16 inch (0.1875 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\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 121169PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714362147122,"sku":"121169PR","price":4667.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e674024faf4c3475d77958ad1e11fbba.jpg?v=1788500243","url":"https:\/\/voomisupply.com\/products\/value-collection-121169pr-set-screw-3-8-16-x-1-2-in-cone-point","provider":"Voomi Supply","version":"1.0","type":"link"}
