Heli-coil 2288-12 Thread Insert Tool 3/4-10 Unc

Product Description

The HELI-COIL 2288-12 is a hand installation tool designed to drive threaded wire inserts into prepared tapped holes. It accepts 3/4-10 UNC inserts and installs them to a depth of 1.125 inches. The tool transfers the insert from the mandrel into the host material by engaging the installation tang, then spinning the insert to the correct seated depth. Machinists, maintenance technicians, and assembly personnel use this tool in repair and production applications where thread inserts restore or reinforce internal threads in metal, plastic, or composite workpieces.

This tool is used wherever 3/4-10 UNC HELI-COIL wire thread inserts are being installed by hand. Common applications include engine repair, heavy equipment maintenance, structural fastener repair, and production assembly lines that require a controlled, non-powered installation method. It is suited for both shop-bench use and field repair work where a power driver is not practical or required.

Key Features

• Sized specifically for 3/4-10 UNC thread inserts
• Install depth of 1.125 inches accommodates standard insert lengths for this thread size
• Hand-operated design requires no power source, making it practical for field service
• Insert Tool type engages the drive tang for controlled, consistent seating
• Minimum thread size compatibility of 3/4-10 keeps the tool matched to a specific insert series

Compatibility

Designed for use with HELI-COIL wire thread inserts in the 3/4-10 UNC thread series. Verify insert manufacturer and series against tool specifications before use.

Installation Notes

Installation should be performed by a machinist or qualified technician familiar with threaded insert procedures. The host material must be drilled and tapped to the correct HELI-COIL oversize tap specification before the insert is driven. Align the tool mandrel with the insert tang before applying rotational force to avoid cross-threading or insert damage. After seating the insert, remove the drive tang per the insert manufacturer instructions using the appropriate tang break-off tool.
