Hillman Self-Piercing Sheeter Screws are metal roofing screws engineered to fasten thin pieces of metal to wood, fiberglass or metal primarily through a pre-drilled, or own generated hole in light gauge metal.

These self-drilling sheet metal screws have a ceramic finish that exceeds the 1000 hour salt spray test, and are recommended for use for treated lumber.
