Manufactured from stainless steel with a bright uncoated finish, this insert accepts a 9\/16-12 UNC thread and measures 0.844 inches in overall length, corresponding to a 1-1\/2D length-to-diameter ratio. The tanged design aids installation by providing a drive point for the installation tool. Machinists, maintenance technicians, and field service professionals use these inserts for thread repair and original equipment assembly across a wide range of industrial and mechanical applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for thread repair or new thread installation in ferrous and non-ferrous base materials including aluminum, cast iron, and steel. The 9\/16-12 UNC coarse thread profile makes it a common choice in structural and general mechanical fastening scenarios where standard unified coarse threads are specified. With 8-1\/4 free coils, the insert provides full thread engagement across the installed length. Each package contains 6 inserts, making it practical for single-job use or bench stock replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-12 UNC thread size with 0.844 inch overall insert length at a 1-1\/2D ratio\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction with bright uncoated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eTanged design for positive engagement with standard HELI-COIL installation tools\u003c\/li\u003e\n  \u003cli\u003e8-1\/4 free coils for full thread contact and load distribution\u003c\/li\u003e\n  \u003cli\u003ePackaged in a quantity of 6 inserts per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and repair replacement thread insert for tapped holes requiring a 9\/16-12 UNC internal thread profile in metal or composite parent materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a compatible HELI-COIL tang drive tool and a properly sized tap to prepare the parent material bore before insert placement. Power down or de-energize any equipment before performing thread repair on in-service machinery. After the insert is seated flush or slightly below the surface, the installation tang must be broken off using a tang break-off tool; retain and dispose of the tang rather than leaving it in the assembly. Follow applicable shop or OEM torque specifications for the final fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12 inches\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: 0.844 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: 8-1\/4\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6 inserts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: R1185-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51985465311538,"sku":"R1185-9","price":55.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7421bc3371afd08adf2e8b3c0395c8a8.jpg?v=1789985467","url":"https:\/\/voomisupply.com\/products\/heli-coil-r1185-9-free-running-insert-9-16-12-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
