Manufactured from 304 stainless steel with a bright, uncoated finish, this insert accepts a 2-56 UNC thread and measures 0.215 inches in overall length, representing a 2-1\/2D length-to-diameter ratio. The tanged design allows installation with a standard HELI-COIL drive tool, after which the tang is broken off flush. Machinists, maintenance technicians, and assembly professionals install these inserts to restore stripped threads or to reinforce threaded holes in softer base materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in precision assembly, maintenance and repair operations (MRO), and original equipment manufacturing where a 2-56 UNC threaded hole requires reinforcement or thread restoration. The 0.215-inch overall length suits thin-section and confined-space applications where longer inserts are not practical. The 304 stainless steel construction makes it appropriate for environments where corrosion resistance is a consideration. This insert is sold individually, though a minimum order quantity of 10 units applies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-56 UNC thread size for fine-pitch small-fastener applications\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction provides corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no coating to affect thread tolerance stack-up\u003c\/li\u003e\n  \u003cli\u003eTanged design for positive engagement with a HELI-COIL installation tool\u003c\/li\u003e\n  \u003cli\u003e0.215-inch overall length with a 2-1\/2D length-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003e9-5\/8 free coils for consistent thread engagement across the insert length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style free running insert for tapped holes requiring a 2-56 UNC internal thread.

Use the appropriate HELI-COIL installation tool matched to the 2-56 thread size to drive the insert to the correct depth. After installation, break off the tang using a tang break-off tool or needle-nose pliers; ensure no tang fragment remains in the hole before fastener assembly. Follow the equipment manufacturer's torque specifications for the mating fastener after insert installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\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: 0.215 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength-to-Diameter Ratio\u003c\/strong\u003e: 2-1\/2D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 9-5\/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: 0.002 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: A1185-02CN215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51994334003506,"sku":"A1185-02CN215","price":24.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0aff8608701b96a29d28fcc9f96826e1.jpg?v=1789991846","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1185-02cn215-2-56-unc-free-running-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
