It installs into a parent material to provide a precision-formed internal thread sized at 5\/8-11 UNC. The insert is manufactured from Grade 304 stainless steel with a bright finish, offering corrosion resistance in demanding service environments. The tangless design eliminates the installation tang removal step, reducing installation time and preventing loose tang fragments in assemblies. Overall installed length is 0.938 inches at a 1-1\/2D ratio. Licensed machinists, maintenance technicians, and MRO professionals use this insert for thread repair and new thread creation in metal components.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for industrial, commercial, and MRO applications where a reliable UNC threaded interface is required. The 5\/8-11 UNC thread size makes it common in heavy mechanical assemblies, structural fastening points, and equipment frames. The stainless steel construction is appropriate where mild chemical exposure or moisture may be present. It is installed using a HELI-COIL compatible tangless installation tool. One insert is included per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTangless design eliminates tang removal and prevents fragment contamination in the bore\u003c\/li\u003e\n  \u003cli\u003eGrade 304 stainless steel construction resists corrosion and oxidation\u003c\/li\u003e\n  \u003cli\u003eScrew-locking design with a maximum locking torque of 300 inch-pounds\u003c\/li\u003e\n  \u003cli\u003eMinimum breakaway torque of 40 inch-pounds maintains clamp load under vibration\u003c\/li\u003e\n  \u003cli\u003eBright finish on coil surface for consistent seating and installation\u003c\/li\u003e\n  \u003cli\u003e8-1\/2 free coils provide full thread engagement across the 0.938 inch installed length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded insert for 5\/8-11 UNC tapped holes requiring a screw-locking helical coil solution in stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a HELI-COIL compatible tangless insertion tool sized for 5\/8-11 UNC; verify tool compatibility before starting work. The parent material must be tapped to the correct HELI-COIL STI tap specification for 5\/8-11 UNC prior to insert installation. De-energize or lock out any equipment before performing thread repair or insert installation on in-service machinery. Do not use standard tap dimensions for the STI tapped hole, as this will result in improper insert fit and reduced holding strength.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 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: 0.938 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: 0.742 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.767 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 8-1\/2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Locking Torque\u003c\/strong\u003e: 300 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Breakaway Torque\u003c\/strong\u003e: 40 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: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang Style\u003c\/strong\u003e: Tangless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Package\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: A3585-10CN938\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52069064769842,"sku":"A3585-10CN938","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78d883c5d78c1902b67cc35ebdbd25a5.jpg?v=1790047482","url":"https:\/\/voomisupply.com\/products\/heli-coil-a3585-10cn938-5-8-11-unc-locking-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
