Heli-coil 2288-7 Thread Insert Tool 7/16-14 Unc

Product Description

The HELI-COIL 2288-7 is a hand installation tool designed to drive threaded wire inserts into pre-tapped holes. It accepts 7/16-14 UNC inserts and provides the controlled engagement needed to seat inserts flush or sub-flush without damaging the host material. The tool uses a mandrel-style tang drive that engages the insert coil and winds it into the threaded bore. Licensed HVAC technicians, machinists, maintenance mechanics, and general trade professionals use this tool when restoring or reinforcing threaded connections in metal and other materials.

This tool is used wherever HELI-COIL wire thread inserts of the 7/16-14 UNC size are installed. Typical applications include thread repair on aluminum housings, cast iron components, steel assemblies, and similar industrial or mechanical work. It is suited for low-volume hand installation in field service, maintenance shops, and production environments where a power driver is not required or practical.

• Hand-operated design allows controlled, torque-sensitive installation without power tools

Compatibility

Designed for use with HELI-COIL wire thread inserts in the 7/16-14 UNC thread size. Intended as the hand installation tool in a standard HELI-COIL thread repair or thread reinforcement system for that thread specification.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional familiar with thread insert systems. The receiving hole must be drilled and tapped to HELI-COIL specification before the insert is installed with this tool. Do not apply excessive force during winding, as this can distort the insert or strip the tapped hole. After seating the insert, break off the tang using the appropriate tang break-off tool per the manufacturer process.
