Heli-coil 2288-5 Thread Insert Tool 5/16-18 Unc

Product Description

The HELI-COIL 2288-5 is a hand installation tool designed to drive threaded wire inserts into pre-tapped holes. It accepts 5/16-18 UNC inserts and is used to seat them flush or below the surface of the parent material during repair or new-assembly work. The tool engages the insert tang and winds the coil into the tapped hole with controlled torque applied by hand. Weighing 0.25 pounds, it is compact enough for use in confined spaces. Licensed tradespeople and maintenance technicians working on equipment with damaged or stripped threads rely on this tool as part of a complete thread repair procedure.

This tool is intended for hand installation of 5/16-18 UNC coiled wire thread inserts in ferrous and non-ferrous base materials. Typical applications include thread repair on machinery, automotive components, aerospace assemblies, and industrial equipment where a stripped or worn internal thread must be restored to OEM specification. It is suited for both shop and field use wherever hand-driven insert installation is required.

Installation Notes

Installation is performed by hand and does not require power tools. Ensure the host hole has been properly drilled and tapped to the correct insert-tap specification before using this tool. Disengage or break off the insert tang after the insert is fully seated using the appropriate tang break-off tool. Follow applicable safety procedures when working on machinery, including de-energizing and locking out equipment before performing thread repair work.
