Manufactured from Grade 304 stainless steel with a bright finish, this insert accepts an M8 x 1.25 metric coarse thread and provides a 2D length-to-diameter ratio with an overall length of 16 millimeters. The locking feature is built into the coil geometry, delivering a maximum locking torque of 6.00 Newton-meters and a minimum break-away torque of 0.80 Newton-meters. Machinists, maintenance technicians, and assembly professionals install this insert to repair stripped threads or to strengthen threads in soft base materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for precision thread repair and new thread installation in metalworking, manufacturing, and maintenance applications where corrosion resistance and thread integrity are critical. The tangless design eliminates the need for tang removal after installation, streamlining the installation process and reducing the risk of loose tang fragments in assemblies. It is appropriate for both production line use and field repair scenarios where M8 x 1.25 metric coarse thread specification is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM8 x 1.25 metric coarse thread for standard metric compatibility\u003c\/li\u003e\n\u003cli\u003e2D length-to-diameter ratio with 16 millimeter overall length\u003c\/li\u003e\n\u003cli\u003eTangless design eliminates post-installation tang removal step\u003c\/li\u003e\n\u003cli\u003eGrade 304 stainless steel construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMaximum locking torque of 6.00 Newton-meters for vibration resistance\u003c\/li\u003e\n\u003cli\u003eBright finish with minimum outside diameter of 9.80 millimeters and maximum of 10.35 millimeters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-locking threaded insert for use with M8 x 1.25 metric coarse threaded fasteners in applications requiring a tangless helical insert with a 2D engagement length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly sized HELI-COIL tap to prepare the parent material bore to the correct diameter before inserting the coil. Power down any equipment and secure the workpiece before beginning thread repair or installation. A dedicated tangless installation tool is required to drive the insert to the correct depth without damaging the coil. Follow the insert manufacturer's installation guidelines and applicable torque specifications for the fastener used in the finished assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.25 Metric Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 16 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 2D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTang Style\u003c\/strong\u003e: Tangless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Outside Diameter\u003c\/strong\u003e: 9.80 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 10.35 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 6.00 Newton-meters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Break-Away Torque\u003c\/strong\u003e: 0.80 Newton-meters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 10-1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts (Per Package)\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: A4184-8CN160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52112015950130,"sku":"A4184-8CN160","price":19.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69768e2ce2ef287af88aee670c0cc1c4.jpg?v=1790077370","url":"https:\/\/voomisupply.com\/products\/heli-coil-a4184-8cn160-m8-x-1-25-screw-locking-insert-2d","provider":"Voomi Supply","version":"1.0","type":"link"}
