It cuts no chips  -  instead, it cold-forms the thread profile by displacing material, producing a stronger thread form with tighter tolerances. Built from high-speed steel with a bright uncoated finish, it is rated for 1\/4-20 UNC threads at a 2B class of fit with an H7 thread limit. The plug chamfer geometry, with 4 chamfered threads, provides a balance of lead-in ease and threading depth suitable for most standard through-hole applications. Overall length is 2.5 inches with a tapping depth of 1.0 inch.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance threading operations in metalworking, HVAC bracket fabrication, electrical enclosure assembly, and light structural work where 1\/4-20 UNC threaded holes are required in through-hole configurations. The BXP series design is intended for use in materials that form rather than cut cleanly, such as low-carbon steels, aluminum, and similar ductile alloys. It is used by machinists, maintenance technicians, and trade professionals requiring consistent thread quality in moderate-volume applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material instead of cutting, producing stronger threads with no chips\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC right-hand thread, 2B class of fit with H7 thread limit\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 4 chamfered threads for controlled lead-in in through-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability in moderate-speed tapping operations\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with standard tapping fluids and cutting oils\u003c\/li\u003e\n\u003cli\u003e1 oil groove supports lubrication flow during forming\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use thread forming tap for 1\/4-20 UNC through-hole applications in standard tapping chucks and holders accepting a 0.255 inch shank diameter with a 0.191 inch square drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThread forming taps require a properly sized forming tap drill  -  use the correct drill diameter for 1\/4-20 UNC form tapping, which differs from standard cut tap drill sizes. Apply a suitable tapping fluid or cutting oil before and during the tapping operation to reduce forming torque and extend tap life. Secure the workpiece and ensure the tap enters perpendicular to the drilled hole to prevent thread misalignment or tap breakage. This tap is not suitable for brittle materials such as cast iron or hardened steel.\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\u003eThread Standard\u003c\/strong\u003e: UNC\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: H7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eApplication\u003c\/strong\u003e: Through-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\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 inch\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\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: 12667-000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BALAX","offers":[{"title":"Default Title","offer_id":52122589004082,"sku":"12667-000","price":38.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6dd0891ffa547459acbfbd8f670a51d.jpg?v=1790085422","url":"https:\/\/voomisupply.com\/products\/balax-12667-000-thread-forming-tap-1-4-20-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
