Review on 🔩 SPAX Screws 4281020400324: 8 Inch & 4 Inch Dimensions for Versatile Applications by Jayshawn Cuatlayol

The best tamping screws of the time! Not only does the star drive hold the screw securely, but it prevents the cam from falling out better than anything else, unless you're a hacker and can't keep the screwdriver perpendicular to your face. I wish they would make a 1 inch version (which they don't). I use them for everything.
