This tanged titanium insert installs into a pre-tapped STI (Screw Thread Insert) hole and forms a 4-40 UNC internal thread. The 0.112 inch overall length gives a 1D length-to-diameter ratio, making it a compact choice for thin or shallow boss applications. Titanium construction delivers high strength with low weight, suitable for aerospace, military, and high-performance mechanical assemblies. Installation and removal are handled by licensed technicians or precision machinists working to spec-controlled procedures.\u003c\/p\u003e\n\u003cp\u003eThis insert is used wherever a 4-40 UNC thread must be installed or repaired in a parent material. Common applications include thin aluminum, magnesium, or composite housings where a fine machine screw thread must withstand repeated assembly cycles without galling or pull-out. The 1D insert length suits shallow bosses or panels where a longer insert will not fit. The tanged design allows positive seating during installation with a standard HELI-COIL installation tool, and the tang is broken off flush after seating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread form for small machine screw applications\u003c\/li\u003e\n  \u003cli\u003eTitanium material  -  high strength-to-weight ratio, corrosion resistant\u003c\/li\u003e\n  \u003cli\u003eTanged design for controlled installation and positive engagement with installation tool\u003c\/li\u003e\n  \u003cli\u003e0.112 inch overall length at 1D length-to-diameter ratio for shallow-boss fitment\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish  -  no added coating to alter dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 free coils providing consistent thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style free running insert for use in any parent material tapped to the corresponding HELI-COIL STI tap specification for 4-40 UNC threads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires the correct HELI-COIL STI tap to prepare the parent hole before the insert is driven. A proper HELI-COIL installation tool matched to the 4-40 insert size must be used to seat the insert without distorting the coil. After the insert is fully seated, break off the installation tang using a tang break-off tool or sharp punch at the notch at the bottom of the insert. Do not attempt to install with a standard tap or driver, as this will damage the coil and the parent thread.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 0.112 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 1D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 2-3\/4\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: Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: A1185-04GN112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51996388163890,"sku":"A1185-04GN112","price":46.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4681371328389e2a424205fb7ff3eb2_09b270e9-e055-4efd-a8e9-d8989bde8bfb.jpg?v=1789993351","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1185-04gn112-free-running-insert-4-40-titanium","provider":"Voomi Supply","version":"1.0","type":"link"}
