Manufactured from 304 stainless steel with a bright, uncoated finish, this insert accepts an M3 x 0.5 metric coarse thread and measures 0.1181 inches (3.0 mm) in overall length, representing a 1D length-to-diameter ratio. It is used to repair stripped or damaged threads or to install precision threads in softer base materials. Licensed HVAC, plumbing, electrical, and mechanical technicians reach for wire thread inserts when restoring thread integrity without replacing the parent component.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for light-duty threaded repair and reinforcement applications across industrial, mechanical, and field-service environments. The tanged design is compatible with standard Heli-Coil installation tooling that engages the drive tang during insertion. The 1D length-to-diameter ratio and 3-3\/4 free coils make it appropriate for shallow boss depths common in sheet metal enclosures, light castings, and precision assemblies where space is limited. Sold as a single insert with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 metric coarse thread profile for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction resists corrosion in demanding environments\u003c\/li\u003e\n  \u003cli\u003eTanged design for use with standard Heli-Coil installation tools\u003c\/li\u003e\n  \u003cli\u003e3-3\/4 free coils provide consistent thread engagement across the insert length\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no coating variables to account for during fit-up\u003c\/li\u003e\n  \u003cli\u003e1D length-to-diameter ratio suits shallow-boss and space-constrained applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Heli-Coil M3 x 0.5 installation tooling and drill-and-tap sets. Compatible with any parent material tapped to accept an M3 x 0.5 Heli-Coil insert, including aluminum, cast iron, and thermoplastic housings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires drilling the parent material to the correct oversize drill diameter, tapping with the appropriate Heli-Coil tap, then driving the insert with the matching installation tool. Power down any equipment and secure the workpiece before drilling or tapping. After seating the insert, remove the drive tang using a tang break-off tool where required by the application. Follow applicable mechanical fastener standards and the equipment manufacturer service procedures for thread repair on safety-critical components.\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: 0.1181 inches (3.0 mm)\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 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\u003ePackage Quantity\u003c\/strong\u003e: 1 insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: A1084-3CN030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52021703016754,"sku":"A1084-3CN030","price":16.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ea93bbdb1ab73c1c9d145c9394f0c75.jpg?v=1790012690","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1084-3cn030-free-running-insert-m3-x-0-5","provider":"Voomi Supply","version":"1.0","type":"link"}
