Built from Grade 304 stainless steel with a bright finish, this insert accepts a 3\/8-16 UNC thread and measures 0.562 inches overall length, corresponding to a 1-1\/2D length-to-diameter ratio. It features 7-1\/4 free coils and delivers a maximum locking torque of 80 in\/lb with a minimum break-away torque of 12 in\/lb. Machinists, maintenance technicians, and assembly professionals install these inserts to restore or reinforce threads in aluminum, cast iron, and other base materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for industrial, commercial, and MRO applications where a 3\/8-16 UNC threaded hole requires locking thread repair or original equipment thread reinforcement. The tangless design eliminates the need for tang break-off after installation, making it well-suited for blind-hole installations and applications where loose tangs cannot be tolerated. The stainless steel construction resists corrosion, making it appropriate for environments exposed to moisture, mild chemicals, or temperature cycling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTangless design  -  no tang removal step required after installation, suitable for blind holes\u003c\/li\u003e\n  \u003cli\u003eGrade 304 stainless steel construction with bright finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread size, 1-1\/2D length-to-diameter ratio, 0.562 inches overall length\u003c\/li\u003e\n  \u003cli\u003eMaximum locking torque of 80 in\/lb with minimum break-away torque of 12 in\/lb\u003c\/li\u003e\n  \u003cli\u003e7-1\/4 free coils for consistent thread engagement across the insert length\u003c\/li\u003e\n  \u003cli\u003eOutside diameter range of 0.452 to 0.472 inches for precise installation fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw-locking insert for applications requiring a 3\/8-16 UNC internal thread with a 1-1\/2D insert length in a standard helical coil installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized HELI-COIL tap to prepare the parent material hole before inserting; standard drill-and-tap procedures apply. Power down or de-energize any assembly before performing thread repair work on live equipment. A dedicated tangless installation tool is required to drive and seat this insert correctly  -  do not attempt installation with standard screwdrivers or improvised tools. Inspect the finished insert for proper seating and verify thread engagement before returning the assembly to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 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: 0.562 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\u003eNumber of Free Coils\u003c\/strong\u003e: 7-1\/4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Outside Diameter\u003c\/strong\u003e: 0.452 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.472 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 80 in\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Break-Away Torque\u003c\/strong\u003e: 12 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: 0.0118 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: A3585-6CN562\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52044274827570,"sku":"A3585-6CN562","price":22.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/108278f3062dacd4799fb18188e8928f.jpg?v=1790029715","url":"https:\/\/voomisupply.com\/products\/heli-coil-a3585-6cn562-screw-locking-insert-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
