Review on 🔩 Metal Threaded Insert - Z LOK by Douglas Davis

This product is great! I was replacing a valve cover on my 2005 Nissan Altima and ended up pulling more than one thread. I thought that was it. I did a little research and stumbled across the spiral coil and gave it a try. It may be good for other things, but not for what I need. Then I stumbled across this product and when I received it I installed it and now my Altima is back on the road with no valve cover issues!
