Built from 304 stainless steel with a bright, uncoated finish, this insert accepts a 2-56 UNC thread and measures 0.086 inches in overall length, placing it in the 1D length-to-diameter ratio category. The free running design allows rotation during installation and removal without locking. Tangless construction eliminates the need for tang break-off after installation, reducing debris and saving time on the assembly line or in the field.\u003c\/p\u003e\u003cp\u003eThis insert is suited for light-duty threaded repair and original equipment manufacturing applications where a 2-56 UNC thread form is required in softer or worn base materials. Typical use cases include precision instrument housings, electronic enclosures, aerospace assemblies, and small-pitch threaded bores in aluminum or magnesium castings. The 304 stainless steel construction provides corrosion resistance suitable for general industrial and light marine environments. It is sold as a single insert with a minimum order quantity of 100 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTangless design eliminates post-installation tang removal and reduces debris risk\u003c\/li\u003e\n\u003cli\u003e2-56 UNC thread size for small-pitch fastening applications\u003c\/li\u003e\n\u003cli\u003e0.086 inches overall length at a 1D length-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003e304 stainless steel construction with bright, uncoated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3 free coils provide consistent thread engagement in the installed bore\u003c\/li\u003e\n\u003cli\u003eFree running coil type allows smooth rotation without locking behavior\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread repair and thread reinforcement insert for tapped holes requiring a 2-56 UNC thread form in parent materials such as aluminum, magnesium, or other soft metals and plastics.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly sized HELI-COIL tap and a compatible tangless installation tool for the 2-56 insert series. The parent hole must be drilled and tapped to the correct HELI-COIL tap drill size before insert installation. Ensure the work area is clean and free of chips before driving the insert. Tangless inserts do not require a tang extraction step after seating, but the installed thread should be inspected with a go\/no-go gauge before returning the assembly to service.\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 Type\u003c\/strong\u003e: Tangless\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: 0.001 pounds\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: AT1185-02C086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":51993711837490,"sku":"AT1185-02C086","price":76.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da9f027fca56306a9fbf2123db036ab0.jpg?v=1789991311","url":"https:\/\/voomisupply.com\/products\/heli-coil-at1185-02c086-free-running-insert-2-56-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
