Deerwood #8 X 1-1/2″ (BLACK) Robertson Square Drive Flat Head W/ Nibs T17 7M Pack (BFSP08112SNF)

Our Square Drive Zip Drivers combines the Type-17 self drilling 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. Box of 7M.
