Drilling Screws for Joining Insulation to Metal


	Polypropylene Washers	Steel Washer

Secure flat roof insulation and membrane materials. These screws have an oversized shank and threads to keep panels from lifting up in high wind. They drill and fasten in a single step, saving time and effort. The small point penetrates light gauge steel, oriented strand board (OSB), and plywood.

Length is measured from under the head.

Polypropylene Washers—Distribute the load to prevent screws from pulling through insulation.

Steel Washers—More durable than plastic, these washers prevent screws from pulling through insulation. Their hexagon shape works with feeding tools that speed up large-scale roofing jobs.

Steel Phillips Rounded Head Drilling Screws

Drill and fasten metal in one step and create a finished look with these rounded head screws. The Phillips drive withstands less torque than a hex drive, so apply even, steady pressure when drilling.

Length is measured from under the head.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
