Manufactured from Grade 304 stainless steel with a bright finish, it delivers reliable corrosion resistance in demanding environments. The insert accepts an M5 x 0.80 metric coarse thread and measures 7.5 mm in overall length, representing a 1-1\/2D length-to-diameter ratio. The tangless design eliminates the need for tang break-off after installation, reducing debris risk inside assemblies. Licensed HVAC technicians, machinists, and maintenance professionals install this insert when repairing stripped threads or building new assemblies requiring a hardened thread form.\u003c\/p\u003e\u003cp\u003eThis insert is suited for thread repair and new-build applications in light industrial, HVAC equipment, and general mechanical assemblies where an M5 x 0.80 metric coarse thread is required. The 1-1\/2D length provides a balanced grip-to-depth ratio appropriate for medium-load fastening applications. Its stainless steel construction makes it a practical choice for environments with exposure to moisture, mild chemicals, or temperature cycling. The tangless configuration is preferred in precision assemblies where retaining a broken tang inside a bore is not acceptable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 304 stainless steel construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eTangless design eliminates tang break-off debris after installation\u003c\/li\u003e\n\u003cli\u003eM5 x 0.80 metric coarse thread form, 1-1\/2D length ratio\u003c\/li\u003e\n\u003cli\u003e7.5 mm overall insert length with minimum outside diameter of 6.25 mm and maximum outside diameter of 6.80 mm\u003c\/li\u003e\n\u003cli\u003eMaximum locking torque of 1.60 N\/m with minimum breakaway torque of 0.3 N\/m\u003c\/li\u003e\n\u003cli\u003eBright finish; 6-7\/8 free coils for consistent locking engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread repair and new-build insert for assemblies requiring an M5 x 0.80 metric coarse internal thread with a 1-1\/2D insert length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a proper HELI-COIL or compatible tangless insert installation tool and a correctly sized tap to prepare the parent material bore before driving the insert. Power down and de-energize any equipment before performing thread repair on electrical or mechanical assemblies. Follow the insert manufacturer's tap drill size and tap specifications to ensure proper thread engagement and locking performance. Tangless inserts do not require a tang-removal step, but the bore should be inspected for chips and debris before final assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M5 x 0.80 Metric Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 7.5 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\u003eMinimum Outside Diameter\u003c\/strong\u003e: 6.25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 6.80 mm\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTang Style\u003c\/strong\u003e: Tangless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 6-7\/8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 1.60 N\/m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Breakaway Torque\u003c\/strong\u003e: 0.30 N\/m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: A4184-5CN075\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52107058282802,"sku":"A4184-5CN075","price":23.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f9e0e16fd4e4ba372df5fc17857dec8.jpg?v=1790073983","url":"https:\/\/voomisupply.com\/products\/heli-coil-a4184-5cn075-screw-locking-insert-m5-x-0-80","provider":"Voomi Supply","version":"1.0","type":"link"}
