The insert is manufactured from 304 stainless steel with a bright, uncoated finish and measures 0.75 inches in overall length, corresponding to a 2D length-to-diameter ratio for the 3\/8-16 UNC thread size. It uses a tanged design for installation, allowing a standard installation tool to drive and seat the insert. Machinists, maintenance technicians, and field mechanics install these inserts to repair stripped threads or to provide wear-resistant threaded inserts in softer base materials such as aluminum or cast iron.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications in manufacturing, industrial maintenance, and field repair work where a 3\/8-16 UNC threaded hole requires reinforcement or restoration. With 10 free coils, the insert provides full thread engagement across its 0.75-inch length. It is commonly used in automotive, aerospace, and general mechanical assemblies where thread pullout resistance and corrosion resistance are required. The bright stainless steel finish makes it appropriate for environments with exposure to moisture or mild corrosive conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread size with 0.75-inch (3\/4 inch) overall insert length\u003c\/li\u003e\n  \u003cli\u003eTanged design for use with standard HELI-COIL installation tools\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no coating to affect thread tolerances\u003c\/li\u003e\n  \u003cli\u003e10 free coils providing full-length thread engagement at a 2D length-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eSingle insert per package; minimum order quantity of 5 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any tapped hole requiring a 3\/8-16 UNC free-running wire thread insert.

After driving the insert to the correct depth, the tang is broken off using a tang break-off tool if clearance is required. Always verify the tapped hole is clean and free of debris before inserting. Follow applicable shop standards and torque specifications for the fastener used in the installed insert.\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 in\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: 0.75 inches (3\/4 in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 2D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 10\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\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0114 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: A1185-6CN750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52028714713394,"sku":"A1185-6CN750","price":21.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10d0c7759e0ce617275185e8f3bdff33.jpg?v=1790017985","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1185-6cn750-3-8-16-unc-insert-0-75in-ss-tanged","provider":"Voomi Supply","version":"1.0","type":"link"}
