It uses a plug chamfer to guide thread engagement and a spiral point geometry to push chips forward ahead of the cut, keeping flutes clear during production tapping. Built from high-speed steel (HSS) with a steam oxide coating, this tap handles moderate heat and wear in typical threading operations. The 10-24 UNC thread form and 3B class of fit make it a standard choice for machine screws and fastener holes in general fabrication and assembly work. Overall length is 2.375 inches with a thread length of 0.54 inches.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading through-holes in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. The 2-flute spiral point design is most effective in through-hole configurations where chips can exit forward rather than back up into the flute. Typical applications include CNC tapping, manual tapping with a tap handle, and production drilling-and-tapping sequences in light manufacturing and machine shop environments. Right-hand thread direction matches standard fastener orientation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging in through-hole tapping\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides controlled thread lead-in for consistent engagement\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction withstands heat and wear in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and provides mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3B class of fit meets standard tolerance requirements for most general-purpose threaded assemblies\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup on standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSuitable for threading 10-24 UNC through-holes in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel workpieces.

Always ensure the pilot hole is drilled to the correct tap drill size for 10-24 UNC before threading. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Back the tap out periodically when tapping manually to break and clear chips, and never force a tap against resistance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 3B\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: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.54 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.019 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 287\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: 2880401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732608680242,"sku":"2880401","price":19.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3838e095b088d7f494435a207cbe55aa.jpg?v=1788744946","url":"https:\/\/voomisupply.com\/products\/osg-2880401-spiral-point-tap-10-24-unc-plug-3b-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
