Manufactured from 304 stainless steel, this tanged insert measures 0.38 inches in overall length and accepts a 10-32 UNF thread size. The 2D length-to-diameter ratio and 9-1\/2 free coils provide full thread engagement across a compact installation depth. Licensed HVAC technicians, mechanics, and maintenance professionals use inserts like this to restore or reinforce tapped holes in aluminum, cast iron, and other base materials without full re-machining.\u003c\/p\u003e\u003cp\u003eThis insert fits applications where 10-32 UNF threaded fasteners must seat in a parent material that cannot hold threads reliably on its own. Common installation scenarios include control panel enclosures, equipment housings, motor mounts, and sheet metal assemblies found in HVAC equipment, electrical panels, and light industrial machinery. The tanged design is compatible with standard HELI-COIL installation tooling, allowing the installer to drive and break off the tang after seating in a single workflow.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e304 stainless steel construction resists corrosion and withstands elevated service temperatures\u003c\/li\u003e\n\u003cli\u003e10-32 UNF thread size with 2D length-to-diameter ratio for reliable engagement in shallow bores\u003c\/li\u003e\n\u003cli\u003e0.38 inch overall length fits tight installation depths where space is limited\u003c\/li\u003e\n\u003cli\u003eTanged design works with standard helical insert installation drivers for fast, consistent seating\u003c\/li\u003e\n\u003cli\u003e9-1\/2 free coils distribute clamp load evenly across the full insert length\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 1,000 inserts supports high-volume repair and production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any parent material drilled and tapped to HELI-COIL specifications for a 10-32 UNF free running insert; requires the corresponding HELI-COIL tap and installation tool for proper fitment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a pre-drilled hole tapped with the correct HELI-COIL insert tap for the 10-32 UNF size  -  a standard 10-32 tap is not an equivalent substitute. Use the manufacturer-specified insertion tool to drive the insert to the correct depth without distorting the coils. After seating, break off the installation tang using a tang break-off tool or long-nose pliers, and verify the tang has been fully removed from the hole before reassembly. This work is typically performed by machinists, maintenance technicians, or service professionals familiar with thread repair procedures.\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\u003eOverall Insert Length\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 2D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 9-1\/2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTang\u003c\/strong\u003e: Tanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 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: HELI-COIL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1191-3CN380S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52065905869106,"sku":"1191-3CN380S","price":988.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1401f08f7fcd4eeb1b7e85f69d342a8.jpg?v=1790045174","url":"https:\/\/voomisupply.com\/products\/heli-coil-1191-3cn380s-free-running-insert-10-32-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
