Daggerz™ brand concrete screws are skillfully designed for wood or metal-to-concrete applications. This screw features a trim head that conceals the screw and provides a smooth finish. The Hi Low threads allow the screw to be used in either wood or thin gauge metal. It also features deep cutting notches in the thread that reduces driving torque. The proprietary Dagger-Guard coating passes the 1000 hour salt spray test and provides excellent corrosion resistance that's suitable for exterior applications.
