Power Pro Self-Drilling Lath Screws are highly versatile and are used to attach metal to wood, fiberglass, and plastic. These screws feature a self-drilling point that easily creates holes in both thin and heavier gauge metals, while their sharp threads ensure a secure hold by drawing materials together. With a truss washer head that combines the protection of a flat washer with a low profile, a Star/Torx drive to reduce slippage and camout, and zinc plating for moderate rust and corrosion resistance, they offer both durability and reliability.
