Manufactured from 304 stainless steel with a bright, uncoated finish, this insert measures M3 x 0.5 in thread size and 7.5 mm (0.295 inches) in overall length, yielding a 2-1\/2D length-to-diameter ratio. The tanged style allows for installation with a standard Heli-Coil insertion tool. Machinists, MRO technicians, and field service professionals install these inserts to restore or reinforce threaded holes in production and repair applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for metric coarse threaded applications where a durable, corrosion-resistant thread form is required. Common use cases include thread repair in aluminum housings, thin-walled components, and electronic enclosures. The M3 x 0.5 size is frequently encountered in small mechanical assemblies, instrumentation, and light industrial equipment. With 11-3\/8 free coils, the insert provides full thread engagement across its installed length, distributing fastener load evenly through the parent material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 metric coarse thread size for standard metric fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003e7.5 mm (0.295 inches) overall length with a 2-1\/2D length-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eTanged design for use with standard Heli-Coil insertion tooling\u003c\/li\u003e\n  \u003cli\u003e11-3\/8 free coils for full load distribution across the installed thread\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no additional surface treatment to affect tolerances\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 metric coarse M3 x 0.5 threaded holes in production, repair, and maintenance applications across a wide range of base materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly drilled and tapped Heli-Coil preparation hole and a compatible Heli-Coil insertion tool sized for M3 x 0.5 inserts. Power down or de-energize any equipment before drilling or tapping operations. After installation, break off the drive tang using a tang break-off tool; confirm the tang is fully removed from the hole before reassembly. Follow the manufacturer's preparation hole specifications to ensure proper insert fit and thread integrity.\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: 7.5 mm (0.295 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 2-1\/2D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 11-3\/8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang Style\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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: A1084-3CN075\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52098318827826,"sku":"A1084-3CN075","price":32.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08da61d29828725b615a496c1190d12b.jpg?v=1790067479","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1084-3cn075-free-running-insert-m3-x-0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
