Review on 🔩 Chenango Supply Concrete Fasteners Miami Dade Compliant for Screws by Fisseha Rodgers

I used these to fasten 2x4's around a concrete utility room for a workbench, shelves and tool hangers. These screws worked great. I used maybe half the box and didn't break a single one. I followed the advice of others and used compressed air to blow out the drilled holes before inserting the screw and that seemed to help the screw seat better. The hex head made screwing in with an impact wrench very easy. Would definitely buy again.
