Self-Tapping Metal Joist Deck Screws #7 x 1-5/8" are designed explicitly for metal joist applications. This deck screw can be used to attach most types of decking materials such as hardwoods, heat treated lumber (thermally modified), soft woods, composite and PVC with aluminum, stainless steel and steel substructures. Pre-drilling pilot holes through the decking is still recommended.
