Steel Phillips Drilling Screws for Joining Wood to Metal
With Cutting Wings
These screws speed installation by drilling, tapping, and fastening wood and metal in a single operation. Length is measured from the top of the head.
Screws with cutting wings drill a slightly larger hole in the wood to allow for expansion. The wings break off when they contact metal, so the screw can tap the remainder of the hole.
Corrosion-resistant-coated steel screws are a good choice for ACQ-treated (arsenic-free) lumber.
