Review on Powercoil 3532-4GK UNC 4-40 Thread 🛠️ Repair Kit: Enhanced Precision in 1 Kitper Pack by Brandon Rogers

I thought it was a good complete kit with all the parts needed to put in a threaded hole. When I finally installed the insert, the screw would not thread into the hole. I've been using inserts for way too many years and can tell the problem when I see it. They didn't work properly.
