This screw attachment with a ¼″ hexagonal socket and depth stop allows you to perfectly countersink screws in series for terrace construction. By ensuring the correct plunge depth for each screw, you achieve a uniform appearance and prevent the screws from being driven too deep into the countersinks. To do this, you set the depth stop once to the required plunge depth. A ring magnet securely holds the screw to the bit. The plastic cap features a window that provides a clear view of the bit and the screw, allowing you to keep track of your progress. A stainless steel Torx® bit is included, enabling you to screw in gently, thereby minimizing the risk of rust on the screws.
