Daggerz™ brand self-drilling screws are a high quality screw designed for metal-to-metal fastening jobs. The #4 self-drilling point drills through heavy gauge metal easily and eliminates the need for any pre-drilling. The proprietary Dagger-Guard coating passes the 1000 hour salt spray test and provides excellent corrosion resistance that's suitable for exterior applications. A high quality EPDM bonded washer seals around the screw to prevent any water leaks.
