Built from Grade 304 stainless steel with a bright finish, it accepts an 8-32 UNC screw thread and measures 0.246 inches in overall length at a 1-1\/2D length-to-diameter ratio. The insert features 6 free coils and delivers a maximum locking torque of 9 in\/lb with a minimum breakaway torque of 1.50 in\/lb. Maintenance technicians, machinists, and assembly professionals install these inserts to protect parent material threads from wear, stripping, or corrosion in demanding environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use in metal assemblies, industrial equipment, and precision mechanical applications where stainless steel fastener compatibility and vibration resistance are required. The tangless design eliminates the need for tang break-off after installation, streamlining the installation process in production or field repair settings. It is commonly used in aerospace, marine, food processing, and general industrial applications where corrosion resistance is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTangless design eliminates tang removal step during installation\u003c\/li\u003e\n  \u003cli\u003eGrade 304 stainless steel construction provides corrosion resistance in harsh environments\u003c\/li\u003e\n  \u003cli\u003e8-32 UNC thread standard for broad fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eMaximum locking torque of 9 in\/lb resists loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eMinimum breakaway torque of 1.50 in\/lb ensures controlled removability\u003c\/li\u003e\n  \u003cli\u003eBright finish with 6 free coils at a 1-1\/2D length-to-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded insert replacement for applications requiring 8-32 UNC thread repair or reinforcement in metal parent materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized HELI-COIL tap and the appropriate tangless installation tool for 8-32 UNC inserts. Ensure the parent material hole is tapped to the correct thread form and depth before driving the insert. Power down or de-energize any equipment before performing thread repair on live assemblies. Follow the manufacturer's installation tool specifications and applicable torque guidelines for the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 0.246 inches\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: 0.205 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.220 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 9 in\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Breakaway Torque\u003c\/strong\u003e: 1.50 in\/lb\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\u003c\/strong\u003e: Tangless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 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: AT3585-2C246\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52105862512946,"sku":"AT3585-2C246","price":92.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eef56a072d042e88b0c546952440e746.jpg?v=1790072983","url":"https:\/\/voomisupply.com\/products\/heli-coil-at3585-2c246-screw-locking-insert-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
