Impact Tapcon® installation bit. Built-in hex collar serves as a stop feature for drilling the perfect hole depth for Tapcon® screws and other concrete screws. Drill/drive installation sleeve slides over bit and engages with hex collar to quickly drive hex or Phillips head fasteners. One-piece construction withstands higher torque loads than standard quick-change bits. 1/4 in quick change shank is designed to work with impact drivers and reduces slipping in standard drill chucks.
