Built from vanadium high-speed steel with a nitride coating, this tap delivers solid wear resistance and extended tool life compared to uncoated HSS alternatives. It features 3 flutes, a plug chamfer for progressive thread engagement, and a right-hand thread direction. Overall length is 1.937 inches with a thread length of 0.299 inches. The H2 thread limit ensures consistent fit tolerances for 2B and 3B class of fit requirements. Licensed machinists and maintenance technicians rely on this tap for precision thread production in production and repair environments.\u003c\/p\u003e\n\u003cp\u003eThe OSG 2401103 is suited for threading operations in aluminum and cast iron workpieces. The plug chamfer style makes it appropriate for through-hole tapping where the tap can pass fully through the material. It is part of OSG Series 240 and is commonly used in machine tapping setups including CNC machining centers, drill presses, and tapping machines where consistent 5-40 UNC thread quality is required across production runs or field repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVanadium high-speed steel construction for improved hardness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eNitride coating reduces friction and extends tool life in aluminum and cast iron applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows gradual thread engagement, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit supports 2B and 3B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003e3-flute design provides chip clearance and stable cutting action\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 5-40 UNC internal threads in aluminum and cast iron.

Always secure the workpiece firmly and use appropriate cutting fluid for the material being tapped. Ensure the tap is properly aligned with the pilot hole before engagement to prevent tap breakage. Power down or disengage the spindle before loading or removing the tap from the holder.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B \/ 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.299 inches (5\/8 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.937 inches (1-15\/16 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.626 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Nitride\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 240\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2401103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744622805298,"sku":"2401103","price":29.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e88cc5aba0ae0abc3e7d9106948a2f6.jpg?v=1788859105","url":"https:\/\/voomisupply.com\/products\/osg-2401103-straight-flute-tap-5-40-unc-plug-nitride","provider":"Voomi Supply","version":"1.0","type":"link"}
