Built from 304 stainless steel with a bright, uncoated finish, this tanged insert accepts a 7\/16-14 UNC fastener and measures 0.656 inches in overall length, corresponding to a 1-1\/2D length-to-diameter ratio. It installs into a properly prepared HeliCoil-tapped hole and provides a durable thread form that resists corrosion, galling, and vibration loosening. Machinists, maintenance technicians, and trade professionals use these inserts when parent material threads are stripped, damaged, or insufficient for the application load.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for thread repair and new-installation applications across industrial, HVAC, mechanical, and general trade environments. The 7\/16-14 UNC thread size is common in structural fastening, equipment housings, and service panels. The 1-1\/2D length makes it appropriate for moderate-load applications where a full 2D insert is not required. The tanged design simplifies installation with a standard HeliCoil installation tool; the tang is removed after seating using a break-off tool. Sold individually, with a minimum order quantity of 5 units per transaction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-14 UNC thread size for common structural and equipment fastening applications\u003c\/li\u003e\n  \u003cli\u003e0.656 inches overall length at a 1-1\/2D length-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003eTanged design for controlled installation with standard HeliCoil tooling\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no coating thickness to account for in close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003e7-3\/8 free coils providing consistent thread engagement and spring-back retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style free running thread insert for use in any parent material tapped to HeliCoil 7\/16-14 UNC insert specifications.

Power down or de-energize any equipment before performing thread repair on live assemblies. After driving the insert to the correct depth  -  flush with or one turn below the surface  -  remove the tang using a break-off tool. Follow applicable workplace safety standards and equipment manufacturer service procedures when performing thread repair in the field.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 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: 0.656 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: 7-3\/8\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: 0.013 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: A1185-7CN656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51985933205810,"sku":"A1185-7CN656","price":16.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35a510768a2d3d2a10f644ef677737c2.jpg?v=1789985823","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1185-7cn656-free-running-insert-7-16-14-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
