Heli-coil 2288-6 Thread Insert Tool 3/8-16 Unc

Product Description

The HELI-COIL 2288-6 is a hand installation tool designed specifically for driving 3/8-16 UNC thread inserts into pre-tapped holes. The tool engages the tang of a HELI-COIL wire thread insert and winds it into the receiving thread, seating the insert flush or below the surface. It is a manual, non-powered tool suited for bench work, field repair, and production environments where insert installation is performed by hand. Machinists, maintenance technicians, and trade professionals working on threaded repair applications use this tool as part of a complete HELI-COIL installation process.

This tool is used wherever 3/8-16 UNC thread inserts are being installed into metal, composite, or other substrate materials. Typical applications include repair of stripped or damaged threads in aluminum housings, cast iron components, steel assemblies, and similar parts found across HVAC equipment, machinery, and mechanical systems. It is sized exclusively for the 3/8-16 UNC thread specification and is not interchangeable with other thread sizes.

Installation Notes

This tool is used after the receiving hole has been drilled and tapped to the correct HELI-COIL specification for 3/8-16 UNC inserts. Ensure the tapped hole is clean and free of debris before beginning insert installation. Apply the insert to the tool mandrel, align with the tapped hole, and turn the handle to wind the insert in until it is seated at the correct depth. Machinists and maintenance technicians should follow the HELI-COIL installation instructions for proper tang break-off procedures after seating.
