Manufactured from 304 stainless steel with a primer-free finish, it installs into a prepared helical-coil tapped hole to create a durable thread form that meets or exceeds the strength of the parent material. The insert accepts a 10-32 UNF male thread and measures 0.38 inches overall length, corresponding to a 2D length-to-diameter ratio. It features a tanged design to facilitate installation with a standard HELI-COIL installation tool, making it suitable for production and repair applications across a wide range of industries.\u003c\/p\u003e\n\u003cp\u003eThis insert is used wherever a 10-32 UNF internal thread requires reinforcement, repair, or first-time installation in softer base materials such as aluminum, magnesium, cast iron, or plastics. The 2D insert length provides a balanced thread engagement suitable for both lightly and moderately loaded fastener joints. Typical applications include machine frames, enclosures, electronic assemblies, and mechanical subassemblies. It is supplied as a single insert. The minimum order quantity is 10 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003e10-32 UNF thread size with 0.38 inches overall insert length\u003c\/li\u003e\n  \u003cli\u003eTanged design for use with standard HELI-COIL installation tooling\u003c\/li\u003e\n  \u003cli\u003ePrimer-free finish for direct installation without additional surface preparation\u003c\/li\u003e\n  \u003cli\u003e9-1\/2 free coils providing consistent thread engagement across the full insert length\u003c\/li\u003e\n  \u003cli\u003e2D length-to-diameter ratio suited to standard fastener joint requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style free running threaded insert for use in helical-coil tapped holes sized for 10-32 UNF thread repair and reinforcement applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly prepared tapped hole using a HELI-COIL or equivalent STI (Screw Thread Insert) tap sized for the 10-32 UNF insert. Use the appropriate installation tool to wind the insert into the tapped hole until the top coil is flush with or one half turn below the surface. After installation, use a tang break-off tool to remove the drive tang where access allows. Follow applicable equipment manufacturer service procedures and applicable codes when performing thread repair on structural or pressure-bearing components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eCoating\/Finish\u003c\/strong\u003e: Primer-Free\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\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: A1191-3CNPF380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51993720095026,"sku":"A1191-3CNPF380","price":26.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8c008d4037c158a27bc0fc730f2a2a.jpg?v=1789991315","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1191-3cnpf380-free-running-insert-10-32-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
