Stripped out a 3/8-16 threaded hole in aluminum or cast iron? This E-Z LOK kit is your fix. It comes with 10 steel inserts (black oxide finish), the right size drill bit, the correct tap, and a drive tool – everything you need in one box. These inserts are super handy because they have a pre-applied adhesive on the external threads. When you screw them into the freshly tapped hole, the adhesive activates and locks them in place permanently, creating super strong new threads that are often better than the original soft metal. They're perfect for repairing engine parts, machinery, or any project where you need durable threads. The process is straightforward: drill out the old hole, tap it with the provided tap, and then screw in the insert using the drive tool. A must-have for any serious mechanic or metalworker's toolbox.
