Made from 304 stainless steel with a bright, uncoated finish, this insert accepts a 10-32 UNF thread and measures 0.38 inches overall in length, representing a 2D length-to-diameter ratio. It is a tangless design, eliminating the need for tang break-off after installation. Technicians and machinists install these inserts to repair damaged threads or reinforce soft-material threads in metal, composite, or plastic assemblies.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications requiring a clean, corrosion-resistant threaded repair or original-build thread reinforcement. The 10-32 UNF size is common in light mechanical assemblies, electrical enclosures, instrumentation panels, and precision equipment. The tangless configuration is preferred in production environments and tight-access installations where tang removal is not practical. Installation requires a dedicated HELI-COIL installation tool matched to the 10-32 thread size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTangless design eliminates tang break-off after installation\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e10-32 UNF thread size with 0.38 inch overall length\u003c\/li\u003e\n  \u003cli\u003e2D length-to-diameter ratio provides solid thread engagement\u003c\/li\u003e\n  \u003cli\u003e9-1\/2 free coils for consistent load distribution\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-use environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded insert for 10-32 UNF tapped holes requiring helical wire thread reinforcement or repair in metal, composite, or plastic base materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized HELI-COIL tang-free installation tool and a pre-drilled, tapped hole prepared with the corresponding STI (Screw Thread Insert) tap. Ensure the base material hole is clean and free of debris before driving the insert. Power down or de-energize any assembly before performing thread repair work in electrical or instrumentation panels. Follow applicable torque and assembly specifications provided by the equipment manufacturer for the fastener used in the finished thread.\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: Tangless\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: 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: AT1191-3C380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52122346815794,"sku":"AT1191-3C380","price":110.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2c7818a5d6bd4c051f99652ddae60d1.jpg?v=1790085272","url":"https:\/\/voomisupply.com\/products\/heli-coil-at1191-3c380-free-running-insert-10-32-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
