The stainless steel thread inserts create a repaired thread that is harder and more wear-resistant than the original parent material thread, making the repair a genuine long-term fix rather than a temporary patch. Each size in the kit includes the full sequence of tools needed for the repair process: an HSS twist drill to open the damaged hole to the correct diameter, a tap to cut the new thread for the insert, a driver to install the insert, and a tang break-off tool to remove the installation tang once the insert is seated. 110 thread inserts are included across all five sizes. All tools store in a steel carry case with individual compartments. Suitable for automotive engine repair, machine maintenance, 4S shop and professional workshop use, and DIY thread restoration.
