Built from high-speed steel with a bright, uncoated finish, it runs an H2 thread limit for close-tolerance fits. The plug chamfer — typically 3 to 5 threads of lead — makes it suitable for through-holes and most blind-hole applications where a partial lead-in is acceptable. With 3 flutes for efficient chip clearance and a 1-inch thread length, this tap is sized for light-gauge metal and precision assemblies. Machinists, maintenance techs, and HVAC or electrical service professionals reach for STI taps when restoring damaged threads using Helicoil-style inserts.\u003c\/p\u003e\u003cp\u003eThis tap is used in applications where a standard thread has stripped or been damaged and a coiled wire thread insert is needed to restore full thread strength. The 10-32 UNF size is common in electrical enclosures, control panels, HVAC equipment, and light mechanical assemblies. The 2.5-inch overall length provides adequate clearance for most hand-tap wrench setups. It is sold individually and is appropriate for both shop use and field repair work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-32 UNF thread form sized for Helicoil-style screw thread insert installation\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for controlled, close-tolerance thread fit\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides 3-5 thread lead-in, suitable for through-holes and most blind holes\u003c\/li\u003e\n\u003cli\u003e3-flute geometry promotes chip evacuation during hand tapping\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction offers durability across steel, aluminum, and similar materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — Helicoil reference number 3FPB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 10-32 UNF Helicoil-style screw thread inserts in standard STI tap-drill and insert installation sequences.

Ensure the correct STI tap-drill size has been used to prepare the hole before tapping. Back the tap out periodically to clear chips, especially in blind holes. Always de-energize or isolate any equipment before performing thread repair work on energized panels or mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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 \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelicoil Reference Number\u003c\/strong\u003e: 3FPB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPORT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-22589\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51690591158578,"sku":"BDNA-22589","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99358bcc33dfa0a7c42d8a83d3280b91.jpg?v=1788272249","url":"https:\/\/voomisupply.com\/products\/import-bdna-22589-hand-sti-tap-10-32-unf-h2-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
