Abstract: The invention provides an alternative improved use of using screws, spikes and nails in joining pieces of wood. The intent of making use of the above named devices is to use a simple procedure to join separate pieces of wood using the Nail Screw or Twin Spike or Twin Nail. This is easily accomplished by using a Drill and Bit as the primary method by drilling the Nail Screw end into the wood. The secondary method would be to hammer the Twin Spike or Twin Nail using a simple tool fitting over the shank. For either method, in most cases, pre drilling would be appropriate. When using the Nail Screw, pre drilling would simplify the wood joinery. The end result would be that in most cases no metal part is visible after completion of the task.
