Centerline #8 X 1-3/4” Flat Head Square X Self-Countersinking Fluted-Tip Wood Screws, Black, 100-Pack

Each of these screws features cutting nibs under the head that help it sink flush with the surface without need for a countersink bit. In addition, their deep threads offer fast, no-wobble starting. Thanks to the combination square/Phillips drive, you can choose between the positive hold of a square drive bit or the convenience and availability of a Phillips bit. Available in a range of lengths and finishes.
