Drill and Tap screws, or self-drilling screws, enable drilling without first creating a pilot hole. The point on a self-drilling screw is designed to efficiently remove material and precisely size the hole for the thread. Serrations under the hex head provide locking action.

Standard zinc plated fasteners are not suitable for use with pressure treated lumber.
