Centerline #8 X 3” Flat Head Square X Self-Countersinking Wood Screws, Lube Finished, 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 WoodMaster™ serrated threads offer fast, no-wobble starting and reduced splitting. The low-friction lube finish lets them sink in quickly for a tight hold. 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.
