Review on 🔩 SNUG Fasteners SNG481 Phillips Concrete: Exceptional Fastening Performance by Flavio Iyer

These are good for most applications but have some problems with extremely hard industrial concrete. The concrete was so hard that it wore down the threads before we could fully tighten them. But no problem, they were so cheap we just threw them away and brought home a new screw to finish the job. Make sure you use the right size Phillips screwdriver and concrete drill bit to avoid further trouble. They go through regular concrete like butter and hold up REALLY.
