It carries an H2 thread limit for consistent tolerance control and features 3 flutes with a plug chamfer, making it suited for through-hole and moderately deep blind-hole tapping applications. Constructed from high speed steel with a bright finish, this tap delivers reliable cutting performance across a range of common shop and field materials. Licensed machinists, maintenance technicians, and tool-and-die professionals install this tap by hand or with a standard tap wrench in bench and repair work.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use where an STI thread insert is required to restore or create a stronger threaded hole. The 5-40 UNC designation and H2 limit make it well suited for precision-fit insert applications in aluminum, carbon steel, cast iron, and hardened steel. The plug chamfer provides a moderate lead-in of typically 3 to 5 threads, balancing starting ease with the ability to tap close to the bottom of a hole. It fits standard hand tapping setups and is appropriate for both production repair and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread form with H2 thread limit for controlled tolerance fit\u003c\/li\u003e\n  \u003cli\u003eSTI (Screw Thread Insert) profile for use with threaded insert installation\u003c\/li\u003e\n  \u003cli\u003e3-flute plug chamfer design for moderate lead-in in through and blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across aluminum, carbon steel, cast iron, and hardened steel\u003c\/li\u003e\n  \u003cli\u003eBright finish with no coating for straightforward inspection and standard use\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1-15\/16 inches supports use in confined workspaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand tapping applications requiring a 5-40 UNC STI thread form.

Always secure the workpiece and ensure the tap is started square to the hole to prevent breakage. Apply an appropriate cutting fluid for the material being tapped. Inspect the tap for wear or chipping before each use, as a damaged high speed steel tap can seize or break in hardened materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\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: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Materials\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: 6006000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743339479346,"sku":"6006000","price":37.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dca03703dfedfba30127f117b1d670f.jpg?v=1788845846","url":"https:\/\/voomisupply.com\/products\/osg-6006000-hand-sti-tap-5-40-unc-h2-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
