It installs into an 8-32 UNC tapped hole and provides a full-strength internal thread for accepting standard 8-32 fasteners. The insert measures 0.164 inches in overall length, which corresponds to a 1D length-to-diameter ratio. Constructed from 304 stainless steel with a primer-free finish, it delivers corrosion resistance without requiring any coating prep before installation. With 3-1\/2 free coils, the insert is tanged for use with standard HELI-COIL installation tools. This style of insert is installed by machinists, maintenance mechanics, and field technicians performing thread repair or new-hole thread reinforcement.\u003c\/p\u003e\u003cp\u003eFree running inserts of this type are used across industrial, HVAC, plumbing, and electrical applications wherever thread strength and longevity are priorities. They are commonly installed in aluminum, magnesium, cast iron, and other materials that are prone to thread stripping or wear. The 8-32 UNC thread size is standard in electrical enclosures, equipment panels, and mechanical assemblies. The 1D length suits thinner base materials or shallow bosses where a longer insert would bottom out before seating fully.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread size for compatibility with standard inch-series fasteners\u003c\/li\u003e\n\u003cli\u003e0.164 inch overall length with 1D length-to-diameter ratio for shallow-boss installations\u003c\/li\u003e\n\u003cli\u003e304 stainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n\u003cli\u003eTanged design for use with standard HELI-COIL tang break-off and installation tools\u003c\/li\u003e\n\u003cli\u003e3-1\/2 free coils provide consistent thread engagement along the insert length\u003c\/li\u003e\n\u003cli\u003ePrimer-free finish allows direct installation without surface prep\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style wire thread insert for use in standard 8-32 UNC HELI-COIL tapped holes prepared with the corresponding HELI-COIL drill and tap kit for 1D insert length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly prepared HELI-COIL tapped hole drilled and tapped to the correct oversize specification for an 8-32 insert. A standard HELI-COIL insertion tool is required to drive the tanged insert into the prepared hole. Once seated, the installation tang must be broken off using a tang break-off tool before the mating fastener is installed. Ensure the base material is clean and free of chips or debris before starting the insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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: 0.164 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: 3-1\/2\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: A1185-2CNPF164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELI-COIL","offers":[{"title":"Default Title","offer_id":52043221270834,"sku":"A1185-2CNPF164","price":28.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2971f964440e901d0cf7d6f1df28a3e.jpg?v=1790028921","url":"https:\/\/voomisupply.com\/products\/heli-coil-a1185-2cnpf164-free-running-insert-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
