Unlike cutting taps, thread forming taps cold-form internal threads by displacing material rather than cutting it, producing stronger threads with no chips to clear. This tap is ground to a 1\/4-20 UNC thread profile with a Class 3B fit and H5 thread limit, making it suitable for close-tolerance work. The plug chamfer style provides a 4-thread lead, balancing ease of starting with good threading depth. Manufactured from high-speed steel with a bright uncoated finish, the BALAX BXP series tap is used by machinists and maintenance technicians working with tapping machines, CNC equipment, or hand tap handles.\u003c\/p\u003e\u003cp\u003eThis tap is intended for through-hole threading in materials where cold forming is appropriate, including low-carbon steel, aluminum, brass, and other ductile alloys. The plug chamfer makes it suitable for through-holes where the tap can fully pass the material. With a tapping depth of 1.0 inches and thread length of 0.79 inches, it fits standard production and maintenance threading tasks. The single oil groove aids lubrication during the forming process. Right-hand thread direction is standard for conventional fastener applications in general manufacturing, HVAC equipment assembly, and mechanical maintenance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting, producing chip-free, stronger threads\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC thread profile with Class 3B fit and H5 thread limit for close-tolerance applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 4-thread lead for easy starting in through-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ductile metal workpieces\u003c\/li\u003e\n\u003cli\u003eSingle oil groove supports lubrication flow during forming\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment and hand drivers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in through-hole threading applications requiring a 1\/4-20 UNC internal thread with a Class 3B fit.

Apply a suitable tapping fluid or cutting oil rated for the workpiece material before and during tapping. Secure the workpiece fully before beginning and ensure the tap enters the hole perpendicular to the surface to avoid thread distortion. This tap is intended for use by qualified machinists or maintenance technicians familiar with proper tapping procedures and tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 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: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 4P\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.79 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.191 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BXP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: BALAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12665-000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52033614840114,"sku":"12665-000","price":38.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e1a96fedb7160dfd9d15d25109b6dc0.jpg?v=1790021679","url":"https:\/\/voomisupply.com\/products\/balax-12665-000-thread-forming-tap-1-4-20-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
