This jig lets you counterbore screws into the edges of decking to produce a surface free of exposed fasteners. Made of glass-filled nylon with hardened steel bushings, the jig has a central guide hole for driving in line with a joist; the two other guides allow driving at compound angles where access is difficult, such as next to a wall. You simply drill a pilot hole at each joist and then use the jig over each hole to drive the screw at the correct angle.
The jig includes three 1/4" deck board spacers, a 6" hardened-steel stepped drill bit for drilling pilot holes, a special 6" long thin-diameter Phillips/square-recess driver to fit through the guide bushings when driving deck screws, and depth-stop collars for the drill and driver.
For use with deck boards from 3/4" to 1 1/4" thick and the Kreg screws offered separately.
Made in USA.
