Review on 🔩 CONFAST Phillips Concrete Screw Anchors: Enhanced Fasteners for Screws by Justin Dorsett

Pack of 100 for attaching drawers to the patio edge. Easily hammered with a Dewalt impact wrench. I used a hammer drill to drill holes. Trust me, if you have to do 100 of those punches, a punch and punch tool will make your job easier. It took three hours. I didn't have a single broken screw or bar. They tightened and the bindings were tight when it was done. I would buy them again. A #3 Phillips bit is used to drive them. The bit fits them tight. Don't try to control them with anything else.
