Steel Phillips Drilling Screws for Joining Wood to Metal
Without Cutting Wings
With Cutting Wings
These steel screws have an ultra-corrosion-resistant coating that resists corrosion in wet environments. They are a good choice for ACQ-treated (arsenic-free) lumber. 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.
