Review on 🔧 Enhancing Efficiency with Z Threaded Hex Flanged Internal Threads by Mike Woolford

They break very easily when screwed into cherry or oak. First, I used a hex wrench that fits snugly in the socket. I then made 1/2" holes which were cut on my power drill with a forstner bit to get the perfect hole. Then I rotated in the opposite direction with each rotation to make it easier to insert into the tree. I made a quarter turn and carefully tightened them. I even paused to let the metal cool. They were still breaking. I was only able to get them in by narrowing the holes with sandpaper, even then I had to take my time not to break them LQ Threaded Inserts are MUCH more powerful.
