Built from high-speed steel with a bright uncoated finish, this tap produces accurate threads in a wide range of materials including aluminum, carbon steel, cast iron, and hardened steel. The three-flute geometry provides a balance of chip clearance and cutting support, while the plug chamfer allows for progressive thread engagement from the start. The H2 thread limit maintains close dimensional control for consistent insert fit. Overall length is 2.125 inches with a thread length of 0.75 inches.\u003c\/p\u003e\u003cp\u003eSTI taps are used when a threaded hole is being prepared to accept a helical wire insert, restoring or reinforcing stripped or damaged threads in both new fabrication and repair applications. The 8-32 UNC sizing makes this tap a common choice in light-duty mechanical assemblies, electronics enclosures, and precision sheet metal work where machine screw inserts are required. It is suitable for hand tapping operations in maintenance, repair, and production environments across industrial, commercial, and field service settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form engineered for helical screw thread insert applications\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for tight dimensional control and consistent insert fit\u003c\/li\u003e\n\u003cli\u003eThree-flute design balances chip evacuation and wall support during cutting\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides gradual thread engagement, reducing start torque\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles aluminum, carbon steel, cast iron, and hardened steel\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting oils and standard tapping fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in hand tapping operations requiring 8-32 UNC STI threads to accept standard helical wire inserts.

Apply a suitable cutting fluid or tapping oil for the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before starting and back off periodically to break chips. Follow applicable shop safety practices and ensure the correct STI tap drill size is used prior to tapping to achieve proper thread engagement for the insert being installed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Carbon Steel, Cast Iron, Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 126\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: 6008100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739582988594,"sku":"6008100","price":34.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6de99b267d5c6975001092619439928d_c4399056-6c19-4ef4-bcac-bf6f2647da43.jpg?v=1788816577","url":"https:\/\/voomisupply.com\/products\/osg-6008100-hand-sti-tap-8-32-unc-h2-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
