Manufactured from 304 stainless steel, this tanged insert measures M3 x 0.5 thread size with an overall insert length of 3.0 mm (0.1181 inches) and a 1D length-to-diameter ratio. It is installed by machinists, maintenance technicians, and field service professionals working on precision assemblies, equipment repair, and thread restoration applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for metric coarse thread applications requiring a reliable, corrosion-resistant thread repair or thread reinforcement solution. With 3-3\/4 free coils, it conforms to standard Heli-Coil installation tooling and is appropriate for use in aluminum, magnesium, cast iron, plastics, and other materials where thread strength must meet or exceed that of the parent material. It is commonly used in automotive, aerospace, industrial maintenance, and general manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 metric coarse thread size for compatibility with standard metric fasteners\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction provides corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eTanged design for reliable installation using standard Heli-Coil driver tools\u003c\/li\u003e\n  \u003cli\u003e3.0 mm overall length (1D ratio) suits shallow-boss and thin-wall applications\u003c\/li\u003e\n  \u003cli\u003e3-3\/4 free coils ensure consistent thread engagement and load distribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Heli-Coil free running insert for M3 x 0.5 metric coarse thread applications, compatible with corresponding Heli-Coil installation tooling for tanged inserts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires drilling the parent material to the correct Heli-Coil tap drill size, tapping with the appropriate STI (Screw Thread Insert) tap, and driving the insert using a Heli-Coil installation tool. Power down or de-energize any equipment before performing thread repair on live assemblies. After installation, the tang must be broken off using a tang break-off tool; retain and dispose of broken tangs to prevent contamination of the assembly. Follow the fastener manufacturer specifications for torque values, as insert installation does not alter standard fastener torque requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3 x 0.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 3.0 mm (0.1181 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: 3-3\/4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang Type\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: 1000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 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: 1084-3CN030S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51984750772530,"sku":"1084-3CN030S","price":1424.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8275725bb674aff6c52e1a5d714ad78_2cc20e1b-64a3-48fd-9a3f-a60069850aa1.jpg?v=1789985000","url":"https:\/\/voomisupply.com\/products\/heli-coil-1084-3cn030s-free-running-insert-m3-x-0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
