Manufactured from Grade 304 stainless steel, this insert provides corrosion resistance suitable for demanding industrial and mechanical applications. The insert measures 0.246 inches overall length, corresponds to an 8-32 UNC thread size, and carries a 1-1\/2D length-to-diameter ratio. It features a tanged design for installation with a standard HELI-COIL insertion tool. Locking torque reaches a maximum of 9 inch-pounds, with a minimum breakaway torque of 1.50 inch-pounds, ensuring positive thread retention under load and vibration.\u003c\/p\u003e\u003cp\u003eThis insert is used wherever a reliable locking thread repair or thread reinforcement is needed in parent materials that are prone to wear, stripping, or vibration-induced loosening. Common installation scenarios include mechanical assemblies, electronics enclosures, aerospace components, and general industrial equipment requiring 8-32 UNC threaded connections. The Grade 304 stainless steel construction makes it well suited for environments where corrosion resistance is a priority. It is installed by licensed mechanics, maintenance technicians, and assembly professionals working across a broad range of industries. This part is sold in a package quantity of 1,000 inserts.\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\u003e8-32 UNC thread size with 1-1\/2D length-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003e0.246 inch overall length for compact thread reinforcement\u003c\/li\u003e\n\u003cli\u003eTanged design for use with standard HELI-COIL insertion tooling\u003c\/li\u003e\n\u003cli\u003eMaximum locking torque of 9 inch-pounds for vibration-resistant retention\u003c\/li\u003e\n\u003cli\u003eMinimum breakaway torque of 1.50 inch-pounds ensures controlled disassembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-locking thread insert for tapped holes with an 8-32 UNC thread form, compatible with standard HELI-COIL insertion tools sized for this thread series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using the appropriate HELI-COIL mandrel-style insertion tool matched to the 8-32 UNC thread size. The parent material must be drilled and tapped with the correct HELI-COIL oversize tap before insert installation. After seating the insert, remove the tang using a tang break-off tool where required by the application. Ensure the installation area is free of debris and the insert is fully seated flush with or below the parent material surface before assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 inch-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Breakaway Torque\u003c\/strong\u003e: 1.50 inch-pounds\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\u003eTang\u003c\/strong\u003e: Tanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1000 inserts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 3585-2CN246S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51986165465394,"sku":"3585-2CN246S","price":1382.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5e4d62f7177bbc55ab340666e9eb228.jpg?v=1789985964","url":"https:\/\/voomisupply.com\/products\/heli-coil-3585-2cn246s-screw-locking-insert-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
