Sized for a 2-56 UNC thread, this tanged insert measures 0.086 inches in overall length and is manufactured from 304 stainless steel with a primer-free finish. The free running design installs without requiring a locking feature, making it the correct choice when thread engagement strength is the primary requirement rather than prevailing torque. Machinists, maintenance technicians, and assembly mechanics use this style of insert to restore or reinforce stripped threads in metal components across industrial and light mechanical applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for applications where a 2-56 UNC thread form is needed in aluminum, magnesium, cast iron, plastics, or other materials with lower shear strength than the fastener itself. At a 1D length-to-diameter ratio and three free coils, it fits shallow boss geometries where space is limited. The primer-free coating keeps the installation path clean for assemblers who apply their own thread-locking or sealing compounds after installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-56 UNC thread size for fine-pitch, small-diameter fastener applications\u003c\/li\u003e\n\u003cli\u003e0.086 inches overall length with a 1D length-to-diameter ratio for shallow installation depths\u003c\/li\u003e\n\u003cli\u003e304 stainless steel construction for corrosion resistance and long service life\u003c\/li\u003e\n\u003cli\u003eTanged design works with standard HELI-COIL installation tooling\u003c\/li\u003e\n\u003cli\u003ePrimer-free finish allows field application of thread-locking or sealing compounds\u003c\/li\u003e\n\u003cli\u003eThree free coils provide consistent thread engagement without a locking feature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style free running insert for use in any parent material tapped to the HELI-COIL 2-56 UNC insert tap specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly sized HELI-COIL tap and matching installation tool for the 2-56 UNC insert series. Ensure the parent material is drilled and tapped to the correct insert tap drill size before driving the insert. After installation, break off the drive tang using a tang break-off tool and verify the tang is fully removed from the threaded hole. Follow applicable torque and thread engagement guidelines for the fastener and parent material combination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.086 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength to Diameter Ratio\u003c\/strong\u003e: 1D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Free Coils\u003c\/strong\u003e: 3\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: Primer-Free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: A1185-02CNPF086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51967142756658,"sku":"A1185-02CNPF086","price":29.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c08b7507b007fc9785ddb1f450f62ccf.jpg?v=1789950832","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1185-02cnpf086-free-running-insert-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
