Deerwood #8 X 1-1/2″ Robertson Square Drive Flat Head W/ Nibs T17 1M Pack (MFSP08112SNZ)

Our Square Drive Zip Drivers combines the Type-17 selfdrilling point that pre-drills itself with the original Robertson® Square Drive Recess for optimum performance. We then added the nibs under the head to help make this a true “One-Step” fastener. Simply put one on the driver bit and watch it pre-drill and self-countersink itself in most all types of wood. We have combined all of our most popular features into one product and it is quickly becoming the fastener of choice.
