STI taps produce an oversized thread profile that accepts helical coil inserts, restoring or reinforcing threads in soft or damaged base materials. This tap features an H3 thread limit, a 3-flute design, and a plug chamfer for standard through-hole and blind-hole starting. It is manufactured from high speed steel with a bright finish. Overall length is 2 inches, thread length is 0.6875 inches (11\/16 inches), shank diameter is 0.141 inches, and square drive size is 0.110 inches. Machinists and maintenance technicians install this tap by hand or with a tap wrench during repair or production threading operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations that require STI (Screw Thread Insert) hole preparation in materials including aluminum, carbon steel, cast iron, and hardened steel. The plug chamfer  -  with several leading threads tapered  -  provides a balanced starting action appropriate for both through-holes and sufficiently deep blind holes. It is used in maintenance, repair, and overhaul (MRO) settings as well as production environments where threaded insert installation is required at the 6-32 UNC size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSTI profile produces oversized thread for helical coil insert installation at 6-32 UNC\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit provides consistent tolerance for reliable insert fit\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances chip clearance and cutting support\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows use in through-holes and deep blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles aluminum, carbon steel, cast iron, and hardened steel\u003c\/li\u003e\n  \u003cli\u003eBright finish  -  no coating  -  simplifies inspection and suits general-purpose applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with helical coil screw thread inserts in 6-32 UNC applications across aluminum, carbon steel, cast iron, and hardened steel workpieces.

Apply cutting fluid appropriate to the workpiece material before and during tapping to extend tool life and improve thread quality. Ensure the workpiece is secured before starting and maintain alignment perpendicular to the hole. Do not force the tap  -  back off periodically to break chips, especially in blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-32\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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 Size\u003c\/strong\u003e: 0.110 inches\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1810400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742304796978,"sku":"1810400","price":37.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3ca52af9d0f8e22c4609de26bf8df23.jpg?v=1788836622","url":"https:\/\/voomisupply.com\/products\/osg-1810400-hand-sti-tap-6-32-unc-h3-3-flutes-plug-chamfer","provider":"Voomi Supply","version":"1.0","type":"link"}
