Sized for 6-32 UNC threads with an H3 thread limit, this tap produces a 2B class of fit and features a plug chamfer for starting in through-holes or deeper blind holes. The 3-flute geometry provides adequate chip clearance in most metal substrates. The body is ground from high-speed steel with a bright, uncoated finish. Machinists, maintenance technicians, and HVAC or field-service professionals reaching for a hand tap to prep stripped or damaged threads will find this a purpose-built tool for insert preparation.\u003c\/p\u003e\n\u003cp\u003eThe 06CPA is used wherever a Heli-Coil or equivalent wire thread insert must be installed to restore or reinforce a stripped 6-32 UNC threaded hole. Typical applications include repair work on aluminum housings, thin-wall enclosures, and equipment chassis found in HVAC equipment, electrical panels, and light mechanical assemblies. The tap is driven by hand using a standard tap wrench and is suited for low-volume repair or prototype work rather than high-production machining. It is appropriate for use in both shop and field service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size 6-32 UNC with H3 thread limit for Heli-Coil insert preparation\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer start  -  suitable for through-holes and deeper blind hole applications\u003c\/li\u003e\n  \u003cli\u003e3-flute design for chip clearance during hand tapping\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across common metal substrates\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no coating variables affecting thread tolerance\u003c\/li\u003e\n  \u003cli\u003e2B class of fit for standard fastener thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as an STI hand tap to prepare 6-32 UNC threaded holes for wire thread insert installation in standard insert repair kits using H3 thread limit specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is driven by hand using a tap wrench  -  it is not intended for use in a drill press or power driver. The workpiece should be secured before tapping begins, and cutting fluid appropriate for the parent material is recommended to extend tap life and improve thread finish. Follow the insert manufacturer's instructions for correct tap drill size before using this STI tap. Wear appropriate eye protection when tapping metal.\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 UNC\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\u003eClass of Fit\u003c\/strong\u003e: 2B\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: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.194 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.152 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\u003eWeight\u003c\/strong\u003e: 0.001 pounds\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: 06CPA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51989309522226,"sku":"06CPA","price":80.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a34f74ec5d63c79478efed616167a15.jpg?v=1789988159","url":"https:\/\/voomisupply.com\/products\/heli-coil-06cpa-hand-sti-tap-6-32-unc-h3-plug-chamfer","provider":"Voomi Supply","version":"1.0","type":"link"}
