Heli-coil 2299-3 Thread Insert Tool 10-32 Unf

Product Description

The HELI-COIL 2299-3 is a hand installation tool designed specifically for inserting 10-32 UNF thread inserts into pre-tapped holes. It drives wire thread inserts to the correct depth without power tools, giving technicians precise control during installation. The tool is lightweight at 0.17 pounds, making it easy to handle in tight engine bays, control panels, or equipment housings. Electricians, HVAC techs, mechanics, and maintenance professionals use this tool wherever stripped or damaged threads need to be restored using coil-type thread inserts.

This tool is suited for repair and assembly work across residential and commercial applications, including electrical enclosures, HVAC equipment housings, and mechanical assemblies where 10-32 UNF fastener threads have been stripped or need reinforcement. It is used in combination with the corresponding HELI-COIL thread insert and the appropriate drill and tap for a complete thread repair. The hand-drive design makes it practical for field service where power tools are impractical or where torque sensitivity is important.

Installation Notes

Thread insert installation is typically performed by maintenance technicians, machinists, or licensed trade professionals. Before installing, ensure the host material has been drilled and tapped to the correct HELI-COIL specification for 10-32 UNF. Use the hand tool to drive the insert flush with or just below the surface of the parent material. Do not use power drivers with this hand installation tool, as over-driving can damage the insert or surrounding material.
