Manufactured from 304 stainless steel with a bright, uncoated finish, this tanged insert measures 0.324 inches in overall length and is sized for 12-24 UNC thread applications. The coiled wire construction distributes load across multiple thread engagement points, protecting the parent material from wear and allowing stripped or damaged threads to be restored to full-strength specification. Installation requires a dedicated HELI-COIL tap and installation tool. This insert is sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use in metalworking, maintenance, repair, and manufacturing applications where 12-24 UNC threads must be installed or restored in aluminum, cast iron, magnesium, plastics, and other materials with lower thread strength than steel. The 1-1\/2D length-to-diameter ratio provides solid thread engagement depth for moderate load-bearing connections. It is commonly installed by machinists, maintenance technicians, and field service professionals working on equipment assemblies, enclosures, and structural fastening points.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e304 stainless steel construction resists corrosion and withstands elevated service temperatures\u003c\/li\u003e\n\u003cli\u003e12-24 UNC thread size with 0.324 inches overall length and 1-1\/2D length-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003eTanged design for standard installation tooling; tang is removed after seating\u003c\/li\u003e\n\u003cli\u003e6 free coils provide consistent thread form and load distribution\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish  -  no coating interference with thread tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard free running insert for 12-24 UNC tapped holes.
