Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap features a bottoming chamfer with 2.5 chamfered threads, making it well suited for threading close to the bottom of a blind hole. Constructed from high-speed steel with a bright uncoated finish, it measures 2.375 inches overall length with a 0.62 inch thread length. It is installed by machinists, toolroom technicians, and maintenance trades working with ductile metals.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for blind hole applications where thread formation near the bottom of a bore is required. The bottoming chamfer style allows threading deeper into the hole compared to plug or taper chamfer taps. The 12-24 UNC thread standard is common in light mechanical assemblies, electrical enclosures, and instrumentation hardware. The BXB series designation indicates this is a BALAX form tap designed for use in materials such as aluminum, copper, brass, and soft steels where chip-free threading is preferred.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, eliminating chips in blind holes\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer with 2.5 chamfered threads for threading close to the bottom of a bore\u003c\/li\u003e\n  \u003cli\u003e12-24 UNC thread form with Class 3B fit and H4 thread limit for consistent tolerance\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides hardness and wear resistance for production use\u003c\/li\u003e\n  \u003cli\u003eSingle oil groove aids lubricant distribution during the forming operation\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment and tap handles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming tap for 12-24 UNC blind hole threading applications in ductile and malleable workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require adequate lubrication and are installed by machinists or maintenance technicians using a tapping machine, CNC machining center, or hand tap wrench. Always ensure the correct tap drill size for thread forming is used, as it differs from the drill size for cutting taps. Power down and secure the workpiece before tapping operations. Do not use thread forming taps in brittle materials such as cast iron or hardened steel, as material displacement is not possible in those substrates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 0.62 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.165 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: BXB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: BALAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12404-010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52060468150578,"sku":"12404-010","price":38.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdc1e76802da5e1932c80441cd024cbf.jpg?v=1790041105","url":"https:\/\/voomisupply.com\/products\/balax-12404-010-thread-forming-tap-12-24-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
