Manufactured from stainless steel with a bright uncoated finish, this insert measures M3 x 0.5 thread size with an overall length of 4.5 mm, yielding a 1-1\/2D length-to-diameter ratio. The tanged design allows installation with a standard HELI-COIL driving tool, which winds the coil into a prepared threaded hole. Machinists, maintenance technicians, and assembly professionals install these inserts in metal, plastic, and composite workpieces where thread repair or thread reinforcement is required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications demanding a permanent, vibration-resistant internal thread in components subject to repeated fastener engagement. The metric coarse M3 x 0.5 specification makes it a common choice for light hardware assemblies, electronics enclosures, small engine components, and precision instrument housings. Each package contains 12 inserts, supporting multiple repair or production operations from a single order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 metric coarse thread for compatibility with standard M3 fasteners\u003c\/li\u003e\n  \u003cli\u003e4.5 mm overall length at a 1-1\/2D length-to-diameter ratio for balanced thread engagement\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists corrosion and wear over repeated use\u003c\/li\u003e\n  \u003cli\u003eTanged design accepts standard HELI-COIL installation tools for controlled seating\u003c\/li\u003e\n  \u003cli\u003e6-3\/8 free coils provide consistent spring tension and secure locking in the parent material\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for applications where coating contamination must be avoided\u003c\/li\u003e\n  \u003cli\u003ePackage of 12 inserts per order\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 M3 x 0.5 metric coarse tapped holes prepared to HELI-COIL specifications; requires a matching installation tool and correctly sized tap for proper fitment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a HELI-COIL tap to prepare the host hole to the correct oversize diameter before driving the insert. Power down or de-energize any associated equipment before performing thread repair on installed assemblies. Use the manufacturer-specified driving tool to wind the insert flush or slightly below the surface of the parent material. After seating, break off the installation tang using a tang break-off tool where clearance requires removal.\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: 4.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 1-1\/2D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 6-3\/8\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: Stainless Steel\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: 12 inserts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: R1084-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52085692825906,"sku":"R1084-3","price":27.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e212d443286f3b7e696b8003f0151190.jpg?v=1790059156","url":"https:\/\/voomisupply.com\/products\/heli-coil-r1084-3-free-running-insert-m3-x-0-5-12-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
