Review on 🔩 CONFAST Phillips Concrete Screw Anchors: Enhanced Fasteners for Screws by Dang Esq

I am making base panels and a part attaches the underbody panels (Dricore) to the base floor. Every second edge panel must be screwed on. I've tried 3/16 screws from different manufacturers and they didn't work at all. They kept breaking. They work great, fit in and stay put. However, the exercise was a disaster. He lost the "shovel" tip after drilling two holes. In fact, the 2nd hole wasn't even finished yet. I ended up buying another piece (almost 1/3 the cost of the screws!).
