Cortex Concealed Fastening System for Decking is a fast and easy way to conceal fasteners and screw heads when installing decking boards. Installation is easy by using two screws per joist connection. The FastenMaster Cortex box includes everything needed, including screws, plugs and setting tools. FastenMaster recommends installing with an 18 volt cordless drill with 1/2" chuck or a corded drill with 1/2" chuck.
