Built from vanadium high-speed steel with a nitride coating, it delivers improved wear resistance and surface hardness compared to uncoated HSS tooling. The plug chamfer allows controlled thread start and is well suited for through-hole tapping applications. With a 2B class of fit and H3 thread limit, this tap produces threads within tight commercial tolerances. Machinists and tool-and-die technicians use this tap on manual mills, drill presses, and CNC tapping cycles where a straight flute geometry is appropriate for the material and setup.\u003c\/p\u003e\u003cp\u003eThis tap is rated for use in aluminum and cast iron. Its 3-flute straight flute design works best in materials that produce short, broken chips rather than long stringy swarf. The 8-32 UNC thread size is common in machine screws, instrument panels, electrical enclosures, and light mechanical assemblies. It fits standard tap holders sized for the 0.168-inch shank diameter used across this tap size range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVanadium high-speed steel construction for improved toughness over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eNitride coating increases surface hardness and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides a gradual thread start suitable for through-hole applications\u003c\/li\u003e\n\u003cli\u003e2B class of fit with H3 thread limit for consistent commercial-tolerance threads\u003c\/li\u003e\n\u003cli\u003e3 straight flutes designed for short-chip materials such as aluminum and cast iron\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for tapping aluminum and cast iron.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the tapping cycle. Apply a cutting fluid or tapping compound appropriate for the workpiece material to extend tool life and improve thread quality. On manual machines, use a tap wrench with controlled feed; on CNC equipment, verify synchronized tapping parameters match the 32 threads-per-inch pitch before running the cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eOverall Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\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: 0.025 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 2401903\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744715866418,"sku":"2401903","price":25.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18264aece3a1dcf8b41a7e767e2be30b.jpg?v=1788860074","url":"https:\/\/voomisupply.com\/products\/osg-2401903-straight-flute-tap-8-32-unc-nitride-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
