Daggerz™ brand panel clip screws are a high-quality screw designed for fastening panel clips to wood and light gauge metal. They feature a pancake head that has more bearing surface for greater strength. These roofing panel clip screws have a Type 17 point that eliminates predrilling and provides quick and smooth installation into the material. The coarse threads allow for more material to sit between the threads as the screw is being installed. The proprietary Dagger-Guard coating passes the 1000 hour salt spray test and provides excellent corrosion resistance that's suitable for exterior applications.
