Built from Grade 304 stainless steel with a dry film lubricant finish, this insert accepts a 3\/8-16 UNC fastener and delivers a length-to-diameter ratio of 1-1\/2D. At 0.562 inches overall length, it fits compact boss depths while providing a maximum locking torque of 80 inch-pounds and a minimum break-away torque of 12 inch-pounds. Machinists, maintenance technicians, and assembly professionals install these inserts to restore or reinforce stripped or worn threads in parent materials ranging from aluminum to cast iron.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for both original equipment manufacturing and field repair applications where a reliable UNC thread form is required in a corrosion-resistant installation. The 1-1\/2D length ratio is commonly used in medium-duty fastening situations where moderate thread engagement depth is available. The tangless design eliminates the need for tang removal after installation, reducing assembly steps and the risk of debris contamination in blind holes. It is appropriate for use in industrial, commercial, and marine environments where stainless steel corrosion resistance is necessary.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 304 stainless steel construction resists corrosion in demanding service environments\u003c\/li\u003e\n  \u003cli\u003eTangless design requires no tang break-off after installation, simplifying blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eDry film lubricant finish eases installation and helps achieve consistent torque values\u003c\/li\u003e\n  \u003cli\u003eMaximum locking torque of 80 inch-pounds provides secure resistance to fastener back-out under vibration\u003c\/li\u003e\n  \u003cli\u003eMinimum break-away torque of 12 inch-pounds confirms positive locking engagement\u003c\/li\u003e\n  \u003cli\u003e7-1\/4 free coils and 0.562 inches overall length suit shallow-to-medium boss depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread insert for parent material tapped to accept a 3\/8-16 UNC helical coil insert with an outside diameter range of 0.452 to 0.472 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a HELI-COIL or compatible tangless insert installation tool sized for 3\/8-16 UNC inserts. The parent material must be drilled and tapped with the correct HELI-COIL tap to achieve proper outside diameter fit before the insert is driven in. Power down or de-energize any assembly before performing thread repair on components in live systems. Follow the insert manufacturer's installation instructions for proper seating depth to ensure the insert sits flush with or just below the parent material surface.\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\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\u003eNumber of Free Coils\u003c\/strong\u003e: 7-1\/4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 80 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Break-Away Torque\u003c\/strong\u003e: 12 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\u003eCoating\/Finish\u003c\/strong\u003e: Dry Film Lubricant\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: 0.07 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: A3585-6CNW562\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51981760266546,"sku":"A3585-6CNW562","price":20.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89e73e796e04c4ebe0f9bf885a1b6c1a.jpg?v=1789982588","url":"https:\/\/voomisupply.com\/products\/heli-coil-a3585-6cnw562-screw-locking-insert-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
