Made from Grade 304 stainless steel with a bright finish, this tanged insert measures 0.086 inches in overall length at a 1D length-to-diameter ratio. It is engineered for 2-56 UNC thread applications and delivers a maximum locking torque of 20 oz-in with a minimum break-away torque of 3 oz-in. Maintenance technicians and assembly professionals install this type of insert to repair stripped threads or to reinforce threaded connections in metal components subject to repeated fastening cycles or mechanical vibration.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use in light-duty precision assemblies where a compact, corrosion-resistant threaded insert is required. Typical applications include instrument housings, electronic enclosures, small-frame mechanical assemblies, and aerospace or industrial equipment where 2-56 UNC fastener engagement must be maintained under torque cycling or vibration. The tanged design allows standard installation tooling to seat and then break off the tang after installation. Grade 304 stainless steel construction supports use in corrosive or washdown environments where carbon steel inserts would be unsuitable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 304 stainless steel construction provides corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003e2-56 UNC thread size with 1D length-to-diameter ratio for compact thread engagement\u003c\/li\u003e\n  \u003cli\u003eMaximum locking torque of 20 oz-in prevents fastener back-out under vibration\u003c\/li\u003e\n  \u003cli\u003eMinimum break-away torque of 3 oz-in ensures controlled re-entry for serviceability\u003c\/li\u003e\n  \u003cli\u003eTanged design is compatible with standard helical insert installation tools\u003c\/li\u003e\n  \u003cli\u003eBright finish with 3 free coils; outside diameter range of 0.110 to 0.119 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw-locking thread insert for tapped holes requiring 2-56 UNC threads in metal substrates where vibration resistance and thread integrity are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a manufacturer-specified helical insert installation tool matched to the 2-56 UNC thread size. Ensure the host material is tapped to the correct STI (Screw Thread Insert) tap specification before inserting. After driving the insert flush, break off the tang using a tang break-off tool. Always verify thread engagement depth and inspect the installed insert for proper seating before reassembling the fastened joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 1D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Insert Length\u003c\/strong\u003e: 0.086 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Outside Diameter\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.119 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 20 oz-in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Break-Away Torque\u003c\/strong\u003e: 3 oz-in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 3\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\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\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\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: AT3585-02C086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51969520828722,"sku":"AT3585-02C086","price":84.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8fa5f4d39785d1fd59e9e6a30db39f8d.jpg?v=1789952309","url":"https:\/\/voomisupply.com\/products\/heli-coil-at3585-02c086-screw-locking-insert-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
