Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips. This tap is manufactured from high-speed steel and finished with a titanium nitride (TiN) coating that extends tool life by reducing friction and improving wear resistance. It carries a plug chamfer with 3 to 5 chamfered threads for easy starting in through-hole applications. The H4 thread limit and 2B class of fit make it suitable for standard inch-series fastener applications. Machinists and maintenance technicians use this tap in CNC machining centers, drill presses, and hand-tapping setups.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations in ductile materials such as aluminum, mild steel, and similar metals that respond well to the forming process. With a 1 inch thread length and 2.5 inches overall length, it fits standard tap holders and extension holders used in production and repair environments. The 0.2550 inch shank diameter and 0.1910 inch square size are compatible with common tap wrenches and machine holders in this size range. It is a single-piece, individual tap intended for job shop, production floor, or field maintenance use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF thread form with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3 to 5 chamfered threads for through-hole starting\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in production environments\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride coating reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit with 2B class of fit for standard inch-series thread tolerance\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; suited for conventional tapping with applied cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 1\/4-28 UNF plug-style thread forming taps used in through-hole threading applications with compatible tap holders accepting a 0.2550 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps should be installed by a qualified machinist familiar with form tapping procedures and appropriate tap holder torque settings for the work material. Always use a recommended tapping fluid or cutting oil suited to the workpiece material before beginning the tapping operation. Ensure the machine spindle or tap wrench is properly aligned to avoid tap breakage. Do not reverse the tap without confirming the holder and material type are appropriate for back-out forces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: H4\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: 3 to 5\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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2550 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1910 inches\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: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K010373AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739333689650,"sku":"K010373AS25","price":41.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/291404e173011b7b0e392fdca9329022.jpg?v=1788813267","url":"https:\/\/voomisupply.com\/products\/hertel-k010373as25-thread-forming-tap-1-4-28-unf-plug-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
