Sized at 8-32 UNC with a plug chamfer, this tap works in high-production and repair applications where thread restoration or creation to STI (Screw Thread Insert) standards is required. Ground from high-speed steel with a bright, uncoated finish, it features 2 flutes and an H2 thread limit for consistent tolerance control. Overall length is 2-3\/8 inches with a 15\/16-inch thread length. Machinists, maintenance technicians, and repair professionals use this tap when installing threaded inserts to restore stripped or damaged fastener holes.\u003c\/p\u003e\n\u003cp\u003eThe 2CSB is used in applications requiring STI UNC thread profiles at the 8-32 size  -  common in light-gauge metal, aluminum, and other materials where thread inserts reinforce weak or damaged fastener seats. Typical scenarios include aerospace maintenance, automotive repair, industrial equipment overhaul, and any field or shop situation where a standard 8-32 thread has been stripped and a Heli-Coil insert is the specified repair method. The plug chamfer style makes it well-suited for through-hole tapping in most standard repair depths.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSTI UNC thread profile sized for 8-32 Heli-Coil screw thread inserts\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for versatile use in through-hole and moderately deep blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit ensures consistent fit within 3B class of fit tolerance\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral point geometry pushes chips forward, reducing recutting in through-hole operations\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Heli-Coil screw thread insert systems requiring an 8-32 UNC STI tap.

Always use the correct STI tap drill size for the insert being installed before tapping, and apply an appropriate cutting fluid for the workpiece material. Secure the workpiece firmly before tapping to maintain thread alignment. Follow the insert manufacturer's procedure for proper insert installation after tapping is complete.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: STI UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\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: 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: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 9\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1650 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: HELI-COIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2CSB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52061109223730,"sku":"2CSB","price":51.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01d6d310c0c9b56e04e1df07dd47b6a5.jpg?v=1790041559","url":"https:\/\/voomisupply.com\/products\/heli-coil-2csb-spiral-point-sti-tap-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
