Deck Board Spacer / Hole Guide

I was building a wooden deck using 5/4 deck boards and 2x framing and wanted a jig that would make for a consistent board gap as well as insure that my screws are in a nice straight line. This was my idea. The holes are counter sunk to allow for a drill chuck to bottom out without damaging the guide. The flat tab is a 2mm spacer that will go between the boards and the forked sider will fit over the frame material. Enjoy.
