Review on 🔩 SNUG Fasteners SNG487 Diamond Concrete Screws by Ian Bates

I used them to build a staircase down to the basement. To attach the slats I used a Makita rotary hammer and a drill with screws. After drilling the holes, I used these screws to screw the brackets I needed to the concrete wall and floor. They work perfectly and provide very strong holding power to keep the braces in place. The hex head is very convenient and you don't have to worry about removing the cross drive.
