Manufactured from 304 stainless steel with a bright, uncoated finish, this insert provides corrosion resistance and long service life in demanding environments. At 0.492 inches overall length, it represents a 3D length-to-diameter ratio, making it suited for applications where deeper thread engagement is required for reliable fastener retention. Installation requires a proper HELI-COIL tap and installation tool for the 8-32 thread series.\u003c\/p\u003e\n\u003cp\u003eFree running inserts are used where standard thread engagement is needed without locking torque. Common applications include thread repair in aluminum, magnesium, plastic, and other soft or damaged base materials across HVAC equipment housings, electrical enclosures, pump bodies, and general mechanical assemblies. The tanged design allows for installation using a standard drive tool; the installation tang is removed after the insert is seated. This insert is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-32 UNC thread size for standard unified coarse thread applications\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e0.492 inches overall length at a 3D length-to-diameter ratio for strong thread engagement\u003c\/li\u003e\n  \u003cli\u003eTanged design compatible with standard HELI-COIL installation tools\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no coating to interfere with thread fit\u003c\/li\u003e\n  \u003cli\u003e13-1\/4 free coils for consistent load distribution along the thread length\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 with 8-32 UNC tapped holes prepared with the appropriate HELI-COIL series tap and installation tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a HELI-COIL tap sized for the 8-32 insert series and a matching drive tool  -  do not attempt installation with standard taps or improvised tools.
