An ideal fastener for quickly fastening cement board to 20-12 gauge steel studs. The large diameter phillips drive wafer head design resists pullover and the integrated countersinking nibs quickly seat the wafer head flush into dense, hard materials. The self-drilling # 2 point will drill and fasten into metal studs in the 20-12 gauge thickness range. Dagger-Guard 3-layer coating is 1000 hour salt spray tested and is ideal for exterior applications where superior corrosion resistance is necessary.
