STI taps cut oversized threads sized to accept Heli-Coil or equivalent wire thread inserts, restoring thread integrity in stripped or damaged bores. This tap features a plug chamfer for easy starting, 2 flutes for chip evacuation in open-cut conditions, and an H2 thread limit for close tolerance fits. Constructed from high-speed steel with a bright, uncoated finish, it handles general-purpose tapping across a wide range of ferrous and non-ferrous materials. Overall length is 1.75 inches with a thread length of 0.4375 inches.\u003c\/p\u003e\u003cp\u003eThis tap is suited for maintenance, repair, and production tapping operations where thread insert installation is required. Common applications include restoring 2-56 UNC threads in aluminum housings, sheet metal assemblies, and light machinery components. The plug chamfer style makes it appropriate for through-hole tapping where the tap can advance freely through the workpiece. It is typically used by machinists, tool-and-die professionals, and maintenance technicians working with small-diameter fastener threads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSTI thread profile cuts oversized bore for Heli-Coil and compatible wire thread inserts\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides smooth entry and progressive cutting action in through-holes\u003c\/li\u003e\n\u003cli\u003eH2 thread limit ensures close tolerance thread fit for reliable insert seating\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles general-purpose tapping in ferrous and non-ferrous stock\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003e2-flute design promotes chip flow in open through-hole cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 2-56 UNC STI threads to accept wire thread inserts such as Heli-Coil or equivalent products in through-hole configurations.

Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Align the tap perpendicular to the work surface to avoid crooked or torn threads. This operation is typically performed by machinists or maintenance technicians following standard shop practices.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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: 1.75 inches (1.882 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4375 inches (0.322 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7002600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739769340210,"sku":"7002600","price":42.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6c50ccadd05910a1730a831be8ef940.jpg?v=1788818650","url":"https:\/\/voomisupply.com\/products\/osg-7002600-spiral-point-sti-tap-2-56-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
